K&N's Testimonials

We value feedback from K&N users!  Due to differences in driving habits and vehicle designs, results will vary.  The more restrictive the OEM filter is the better your results will be.

I bought a K & N Filter for my 1999 Nissan Maxima GLE about 4 months ago.  I noticed the difference immediately when I started the car and backed down the driveway.  The most impressive thing I found out about this filter was the better gas mileage I was able to get.  I went from 342 miles to the tank up to 375-380 miles to the tank and sometimes higher.  Thanks for a great product.

I recently installed a K & N Air Charger on my 2003 Toyota Tundra, 4.7L V-8, the difference is amazing, I noticed an immediate change in acceleration and torque, I have also have cat-back dual exhaust on it and the difference
in the sound is very impressive, it was also very easy to install, with so many companies that have a fly by night attitude it is very nice to find one that is as reliable and straight forward as K & N.

Thanks Guys,

Everyone I know has a K&N filter in their car and truck. So I decided to put one in my supercharged T-maxx(nitro r/c car). My truck ran so much better.  I got more power and better fuel economy.  I went from running my truck from 12 minutes to 14-15 minutes.  It not only performs great it also looks great and the supercharger works a lot better because it can pull a lot more air through the K&N than the other foam filters that are out for r/c cars.

This summer I purchased a new (2003) GMC half-ton stepside with a 4.8L V8.  At the first oil change interval, I installed a K&N replacement air filter.  The installation instructions were great & the whole process took 
maybe five minutes.  Gas mileage IMMEDIATELY improved over 1 mpg & there is a noticeable increase in power.  In fact, I think the mpg would be even higher if I weren't having so much fun with the throttle response.  Be that as it may, getting almost 21 mpg with a full-size pickup with a V8 is impressive!  Thanks for the great product. This has to be the #1 simplest, most cost-effective way to increase power & decrease fuel consumption!

I dropped a K&N air filter into my Nissan spanking new Terrano2 4X4: Wow what a change.  The diesel consumption has decreased, the linearity of the acceleration is xx times better and the whine of the turbo is incredible.  Overall off and on road engine function is much better.....and air filter cleaning is a breeze!!

All too often companies don't get positive feedback.  This is to tell all who have put out a great product: GREAT JOB!  I have a 2000 Wrangler Sport) JEEP).  I have the K&N Air Filter and just put in a K & N oil filter and I have to say the air filter made a huge difference and the oil filter is great!  I love the 1" nut thing!  Great to put on and off!
Thanks for a great product line and keep the good work up!

I have a 1999 Saturn SC2 and have been looking for an upgrade for the factory air filter for awhile, you know one that wont cost to much, at least until I have the money to do more to my car, anyway and the 33-2055 air filter has really done the job.  I get much better gas mileage, ranching from 27mpg to 30mpg where before I was getting between 23mpg and 25mpg at best.  It even sounds better, and I don't have to replace it or even clean as often as the factory filter.  It's been great and has definitely saved me money on gas and filters. 

Thank You K and N,

Seeing the commercials on the speed channel got me thinking about my 1996 Dodge Dakota 4x4 with V-6, with a lot of miles.  Needed a boost of power and mileage.  I had second thoughts buying the K & N air filter, due to the price.  Installed and started up the engine and could tell a difference , just idling.  Power and mileage increased. While accelerating can hear it sucking air.  Could not before the K & N air filter.  Purchased and 2003 Dodge Dakota 4x4 with V8, first thing I did was install a K & N air filter.  Did not have second thoughts about it, after hearing and feeling the results from the first K & N air filter.

Just wanted to drop a note to say thanks for making excellent products and a website to access all of the information about them.  I bought a new car and was able to find a filter number and a place to purchase it and was done in a few minutes.  All 6 of my vehicles run with K&N, including my 4-wheeler and my Harley.

I own an 85 Mazda rx7 12a non-turbo.  I have used the K&N filter ever since I bought the car.  Since I have no reference that it was performance improvement I'm unable to tell if it is an improvement.  The car however does 25mpg even though most RX7 owners claim 18-20 at best.  But I have to say, the filter picks up all kinds of crap and you can use it for a year or 2 before cleaning it.  I bought a can of Recharge for it recently for $7.00 and I used very little of it. I say this filter will pay for itself within 2 years maybe sooner.  Since I believe the average cost of a replacement throw away filter is $10.00 and you replace it every 10-30k miles.  I know that I put at least 50k on the K&N filter before I cleaned it, and even when dirty the car performed great.

I own a 2003 Oldsmobile Alero with the 2.2 Ecotec, and I installed a K&N air filter.  I can't even express in words how much I love this filter.  The minute after I installed it and reset the cars computer, I went for a drive and the car felt like it had a different engine in it.  The throttle response and acceleration is much quicker.  On the highway, it speeds up now without having to downshift to a low gear.  I am amazed and I will highly recommend this filter to everyone. 

Thanks K&N for such a great product,

I have just installed a K&N high flow filter to my 1995 Mercedes c250 Diesel that has covered the starship mileage of 4005,000 miles.  The difference to the performance and running is incredible.  It runs much smoother than before and is a lot more responsive and doing 3mpg more.  Fantastic product, will be putting one on the wife's 1996 Honda Civic VTEC as soon as poss.

Excellent Results
Just wanted to drop a line to let you know how pleased I am with my K&N FIPK.  As soon as I opened the box, I noticed how detailed the installation instructions were.  I followed the instructions step-by-step, and they covered absolutely everything I ran into during the installation (pictures were great, too).  Too many times aftermarket part installation instructions are vague, at best, but yours were perfect!  Everything went together as specified, no missing parts, clear instructions, and immediately noticeable power increase.

One happy customer,

Dear K&N,
Iíve just completed installing an FIPK in my Frontier.  I noticed the performance improvement immediately.  But that is not why Iím writing.  The installation instructions that came with the kit were the best I have ever used.  The pictures were accurate for my vehicle and the step by step guidance made for an easy install.  Who ever wrote the instruction manual deserves a lot of credit. Congratulations on a truly excellent product.

I have just installed one of your air filters in my 2000 GMC Sierra extended cab and love it.  I could not believe it would have this big of impact.  I am thinking now of installing one in our 1999 Chrysler Concorde.  Keep up the good work and I appreciate anything that can help in this economy of ours today.  A dollar doesn't go as far as it used to, but in this case it DID.

I purchased a K&N HA1330 for my Honda VTX 1300 Retro stock air box.  The installation was very easy as the new air filter fit perfectly.  On my first ride, I was astonished at the additional performance I received.  My bike idled better when cold and the improved acceleration was very noticeable.  I would recommend a K&N filter replacement for all stock filers.

Never heard of your reputation before today, but with friends advice I installed the 33-2175 air filter into my 1999 Dodge Dakota.  Wow!  From the moment I started the truck, I could hear and feel more power.  No more hesitation during shifting, and a clean, effortless drive.  

Very Happy, thanks,

I own a 1997 Mustang, 3.8L engine with about 70,000 miles on it.  I was experiencing a hesitation at low speeds and the engine did not seem to be getting enough air until I was already in 3rd going into OD.  I decided to spend the money on a K&N filter after a co-worker bought one for his Ram Truck and told me how much it improved his performance.  I did not believe an air filter would do to my car what he was saying it would.  After buying it and installing it, I could not believe how much your air filter has improved my car's performance.  The hesitation is gone and so is the $20 I bet my friend Bob Cobbleson that the filter would not remove the hesitation.  Great product, Thanks

Excellent product
I own a 2000 Dodge Ram 1500 2WD with a 5.2L V8.  I had been hesitating buying one of these air filters, mainly because it is $50.00.  Well, I purchased one today and installed it.  After taking it for a test drive, I could not believe the difference it makes.  My engine now sounds like it doesn't have to work as hard and there is no hesitation in acceleration.  Also, the rpm's when idling went from approx. 800 to about 600.  I'll be checking my gas mileage over the next couple of weeks to see what kind of increase I will have.  Keep up the good work.

P.S., I'll be buying one for my Buick Century as soon as I can.

I own a 1996 Honda Civic EX with almost 110,000 miles on it. A few months ago I was becoming frustrated at its ever decreasing gas mileage (26 and dropping).  I found it needed new plugs, which brought it to 29 average, but I demanded more.  At this point I decided to spend the money and buy a FilterCharger for it.  Much to my surprise, it felt like a new car and had phenomenal power again once the filter was installed.  When the VTEC kicks in, it really pulls ya into the seat, and best of all, I could get 33 mpg driving 3 miles to work.  It gets upwards of 36 on the highway now.

I was so pleased with the filter that my father bought one for his 2002 CR-V.  The difference was even more astounding on his vehicle.  With AWD he can break all four tires free on dry pavement-in an automatic-something it would never do before (he was driving).  He even gets 27 mpg on a vehicle that the EPA says should get 22/26.
Thanks again for such a great product.

I installed a K&N air filter at approximately 12,000 miles to avoid the lifetime replacement costs of the stock filters. I'm sorry that I waited so long.  One of the things that I discovered when I purchased this vehicle was that it really gets horrible gas mileage (10-12 city 12-14 highway) for the size vehicle it is (2 door 2wd).  I saw no improvement the first month, but someone told me it would take the computer a while to adjust.  It did.  WOW!  I now get approx 14mpg in town and just recently got 20mpg on my last complete tank of gas.  In the last 10 months or so this filter has paid for itself several times over.  It is amazing to me what a difference a filter can make..........

Approx. 6 months ago I purchased a drop in Filtercharger filter for my 1994 Ford F150 Pickup.  This vehicle is equipped with the non-mass air Inline 6 (300 CI).  Within 100 miles of installing this filter I noticed approx a 1 MPG increase and when cruising or towing on the highway I feel as if I have gained a significant amount of power.  The addition of a free flowing exhaust has also made a definite increase in performance, but simply the filter alone made it worth the $50 I spent.  I would do it again in a heart beat. 

Thanks for making such a great product!

I have put the K&N filter on my 2003 VW GTI 1.8T.  I have felt such a big difference in speed and acceleration.  It's made my car sound a little better with my exhaust.  Both of these products have made my car fast.  But I must say that the Filter I got was def. a great buy!!  I hope you post this on your site!!!!

Thanks a whole lot,

I own a 2000 VW Jetta 1.8TDI.  I just came back from a test drive after installing the K&N filter to replace the OEM and I already noticed quite a difference in power.  The great thing about this filter was that it took about 10 minutes to install and the rewards were awesome.

I use the car for business purposes and am currently getting approx 62 mpg. I hope to do even better with the new filter.

Only one thing I can say to sum up...."a lot of bang for your buck".  I will be putting one in my 4 Runner ASAP.

I bought a 98 Astro van 1-1/2years ago.  During that time it's seen a lot of highway miles averaging 24 mpg with the paper filter.  I decided that replacing the filter( @ $12.00/paper) was a waste of money and decided to purchase a K&N.  The only reason I didn't do it sooner is the $75.00 initial purchase price (Canadian).  I can tell you now, that was a VERY big mistake waiting like I did.  I now get 26mpg highway and it paid for itself in 4 months.  The only complaint I have is K&N does not make an air intake system to compliment its filter for 98 Astro Vans.  With gas prices currently (Edmonton) at $3.00/gallon (sometimes higher) I know for a fact that item would sell.  Anything (almost) to help with power production and increase fuel mileage would be an asset here.

Update on my July 15, 2003 submission to K & N on my results

To Whom IT May Concern,
I must say that I am very impressed with your product.  When I installed part number 33-2277 on my 2003 Honda Accord EX V6, I initially tested its performance on a closed track.  Well after some additional testing recently, something interesting was discovered.  On a certified Dyno machine, the stock wheel horse power and torque increased from 204.5 hp and 180.7 ft/lbs to 216.3 hp and 191.4 ft/lbs! The flywheel horse power rating at 240 hp is likely 250 hp using the standard calculations.  What was most interesting is how the power curve changed.  The engine developed a flatter torque curve with a peak at 4,750 rpm as opposed to the 5,000 rpm stock reading. The same results followed with the horse power delivery.  I don't believe hype, so the math results tell the story.  After using this product for 90 days, I re-tested the performance results at the same track, and here is what happened: 

0-60 7.0 seconds stock

0-60 6.87 seconds K & N installed July 2003

0-60 6.63 seconds K & N after 90 days

1/4 mile 15.5 seconds @ 92 mph stock

1/4 mile 15.1 seconds @ 94.2 mph K & N installed July 2003

1/4 mile 14.8 seconds @ 97.8 mph K & N after 90 days

Top Speed (certified with a calibrated and properly operated radar gun)

138 mph stock

143 mph K & N installed July 2003

146 mph K & N after 90 days

Gas Mileage (measured with the on-board Honda Navigation and mileage calculators)

25.0 mpg city, 31.0 mpg highway stock

26.0 mpg city, 33.5 mpg highway K & N installed July 2003

26.4 mpg city, 33.7 mpg highway K & N after 90 days

Note: When the testing was being completed, the gas mileage for that day was 17.2 mpg.  Obviously, this type of driving was not usual and customary, and thus was not included in the overall gas mileage calculations. 

Additional testing was conducted and across the board increases in performance in 5-60, 20-40, 30-50, and 0-100 mph tests were very apparent.  I have discussed my findings with some Honda experts and they say that part of the results should be credited to the on board computers for the car.  They say that engine computers have likely remapped the fuel/air mixtures to take advantage of the new levels of air available in the intake as a result of the use of your product.  This makes sense to me.  My neighbor installed a K & N filter in his BMW M5 and ZO6 Corvette and saw similar performance increases.  I hope that anyone who reads this testimonial understands that these results are facts, that should be easily repeatable with other vehicles.

I have a 1989 Acura Integra with 237,000 kilometers (147,000 miles), which anyone who knows me personally, is a car I thoroughly enjoy and pride on maintaining and ensuring everything is working at peak performance.  Like most Honda vehicles, it loves to rev and rev high to reach its peak performance! 

Going through my service records this week I realized I was overdue for a new air filter.  After years of seeing your product ads,  I decided I would give it a try.  I removed the old stock filter, which was quite dirty and dusty and carefully put in my new K&N and went for a drive.  In a word: Sweet! 

Of all the years I've owned the vehicle, I have never felt this type of throttle response above 4000 rpm which is normally where the power is for this highly compressed car!  With the K&N, mid range throttle response was just superb.  The response was instantaneous and ran so effortlessly.  The improved acceleration was very noticeable to me!  Just love it!

I got my '03 Chevy Silverado 4.8 a month ago.  Within 2 weeks I put a FIPK II on it and it was like a totally different truck.  Pulling out after installation, my first great impression was the sound of my truck.  It gave it a nice and powerful sound and excellent power boost!  I haven't quite figured out the mpg gain but there is one!  I haven't had my first oil change but you better believe I'll be putting a K&N on!!   -Thanks for a great product

Hi there,
I recently installed a generation 2 FIPK in my 5 speed 2001 Mustang GT . I didn't expect much since I had already installed a K&N Filtercharger and removed the air silencer, but sure enough, the FIPK produced a power difference I could feel.  That 2nd gear shift makes a much louder chirp now!

Thanks for the ponies,

I have been using K&N air filters for many years.  I have used them in 1978 Mercury, 1987 Jeep Wagoneer, 1976 Ford F150, 1982 Ford Conversion Van, 1990-1994 and 1996 Dodge Grand Caravans, 1997 Dodge Dakota. 1997 Polaris 4x4, 1982 Silverwing 1971- 1973 Cub Cadet 12hp mowers.  The least MPG I have seen in any of these applications was 1.1 MPG and my Dakota was 3.6 MPG and the service vehicles (mowers and 4wheeler) are all easier to start and show real improvements when working.  I put between 30,000 to 40,000 miles on a year in all types of conditions.  The 1996 Dodge Grand Caravan we own right now has 207,000 miles on it and it uses NO oil (a testament to a good filtration) has good response when accelerating and still beats the listed MPG for when it was new with K&N air filter in place.  Recently while attending a tradeshow in Terre Haute, Indiana K&N had a booth set up.  I asked the gentleman about a FIPK for my 97 Dakota with the 3.9L and it is currently not listed as available, BUT he gave me the K&N toll free number and a ladies name to speak with.  I left a message on her voice mail and she actually called me back the same day! (highly unusual from most companies)  She is at this moment researching to see if one is going to be available soon.... Not only can I highly recommend the product but I can now truly recommend the employees of K&N.  Another great thing about the gentleman at the booth was when discussing the oil filters he would not discredit or put down any competitor.  He told me facts and let me draw my own conclusion.  (Oil change is on my list of things to do next week complete with K&N filter #HP2004)  I can see that I can actually get the life out of the synthetic oil I use without the fear of the filter breaking down as quickly and with the extra heavy canister no more torn up cans trying to get them off the vehicle, just use a wrench! 

Although I currently own only few of the vehicles I listed above and have never had the opportunity to test the 10 year 1 Million mile warranty I would have to say that this is fact! not hype. Why?

* The quality of the product? Superior, every application I have tried has been a real success!
* The ease of finding the right part? Website makes this so easy this saves allot of time at the parts store, and if in doubt call the 1-800.  The availability of finding a filter by size instead of application makes it
a snap to get filters for mowers and other odd equipment.  Then find a good dealer from the website.
* The people? Outstanding! Employees don't offer this level of service and friendliness without having a company that supports them.  K&N has not tried to sell me what might work only what is proven!

I look forward to using your filters as long as you make them.

I purchased a 2000 Ford E-150 Conversion Van in December of 2000.  The first thing I did was replace the stock air filter with a K & N filter.  The performance and gas mileage for a 7500 lb van is amazing.  At 75 MPH with out the A/C running, I obtain 17 MPG.  With the A/C going I receive 16.2 MPG.  Thanks for all the R & D your company invests into your products.

I must say I was skeptical at what an air filter could actually do for me.  Now that I have switched and had the K&N filter in my Explorer for just over a week now I can actually tell a difference in take off, power, and gas mileage.  We took a trip that was a 6 hour drive both ways, I didn't keep track of how many miles it was, however I did check my mileage.  Before I was getting 16 mpg on the highway, and on our trip we were averaging 19 mpg.  My explorer is a 93 with 173,000 miles on it too, so it is not a new one by any means.  I have actually been very impressed with the performance and I have been telling my friends.  With a product that really works how it says it will, I don't mind putting the decal sticker on my back window and giving you some free advertising.

Purchased my air filter about 4 years ago for my 94 Chevy Cavalier.  I was averaging about 28mpg and when I installed the filter I gained about 4 extra miles.  This product is well worth the cost and I will continue to purchase these filters for future cars that I own. Great Product!!!

I have used your filters for some time, primarily for increased performance in my Harley-Davidson motorcycles. Any Harley owner who has not completed the H-D Stage One upgrade (K&N Air Filter, carb re-jet/EFI adjustment and low-resistance exhaust) is not taking full advantage of their bike's performance capabilities.  The K&N High Flow Air Filter is a pivotal part of this important upgrade.  I also use the chrome K&N oil filters and synthetic 20W50 in my Evolution and Twin-Cam powered bikes for the ultimate in lubrication and wear protection.  I especially like the back flow valve that helps prevent dry starts. 

Of course, K&N filters are also used on my 2003 GMC Sierra HD pickup for the same reasons. Keep up the good work in producing top-notch performance filters.

Attention all S2000 lovers - get yourself a K&N now.  I put one in my Honda a few months ago and the increase in both gas mileage and horsepower is definitely noticeable.  On top of that, that's one less part to buy when you service your vehicle.

I take my S2000 out in the mountains quite frequently, and I've noticed a increase in acceleration when I need to go from about 20 - 60 mph in a hurry.  If you love your car like I love mine, put in a K&N now.  It's easy, and it's only 3X the cost of a paper filter - it pays for itself in only two years.  Thanks K&N!

I just purchased a K&N Filter for my 97 Dodge Caravan.  Immediately I noticed an improvement in performance and after putting on 1800 kilometers on our trip this week, I can honestly say that our family Caravan had a dramatic increase in fuel economy.  It has already paid for itself.  I would be happier if you made a Fuel Injection Performance kit for the Dodge Caravan so us family types can attain more benefits from K&N.  Great product!!!

To K&N, I started using your air filter on my 2000 Harley Davidson Dyna Wide Glide when it had 0 miles on it.  I am a certified Harley Davidson Technician.  It gave me the easiest and fastest (installment wise) zip to my Bike.  Yes sir, If any one wants to know how to get that extra! kick in acceleration and long road performance, I suggest your Air Filters.  Plus they are reusable.  Just buy the cleaning kit and there you go, good for 10 years or the million miles.  I've only just now noticed you have oil filters for my Harley.  Am definitely going to try one of those.  My Dodge Ram 1500 4x4 has your air filter and oil filter.  I should buy your stock, are you open to the public?  Thanks K&N.

I have always heard about K&N filters but honestly was a little skeptical that I would see that much difference, boy was I wrong.  I have a 2002 Hyundai Accent GS.  The first drive to work with my new filter was great!  The car is more responsive during take off and generally just feels more powerful (and even sounds cool too).  I am anxious to check my gas mileage at my next trip to the pump.  Now I will certainly buy a K&N filter for my '67 Impala as well. Thanks for a great product!
