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.

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!
November 11, 2003
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!!
November 11, 2003
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.
October 22, 2003
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.
October 22, 2003
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,
October 22, 2003
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.

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,

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.

highly recommend this product for anyone looking to improve the
performance of the Chevy Blazer.

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.
September 30, 2003
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,
September 26, 2003
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
September 24, 2003
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.
September 23, 2003
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.
September 23, 2003
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!
September 23, 2003
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,
September 17, 2003
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
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.
Praising K&N to everyone I see
September 15, 2003
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
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
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

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
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.
August 25, 2003
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.
August 25, 2003
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.

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

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!
August 18, 2003
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!
