You should change the engine air filter in your BMW 3-Series every 10,000 miles and more often if you drive on a lot of unpaved roads or live in a dusty or desert environment. The air filters protect the air intake system, valves, pistons, cylinder walls, and engine oil from dust and debris that can be sucked in under normal operation. Replacement is a snap and should take only take 30 minutes or so.

Air filters are like oil in that you will no doubt hear discussions on the different types of air filters used in vehicles. There are basically two different types of air filters: the stock paper or cloth air filters and aftermarket units. These aftermarket units utilize an oil-soaked fabric to achieve freer air flow. While this may sound good, many aftermarket filters also do not filter as well as the stock units, in addition the oil can damage the MAF. The various horsepower claims of some aftermarket filters are somewhat suspect. The primary advantage of the aftermarket units is that you usually only have to purchase one, and it will last the life of your car. The bottom line is to carefully research any aftermarket filter before you install it to your car. Make sure that it filters as well or better than the original BMW specifications for your year car.

The air filter and air filter housing (red arrow) are located on the right side of the engine bay just in front of the shock tower.

There are four metal clips that hold the lid of the housing in place (red arrows).

There are four metal clips that hold the lid of the housing in place (red arrows). One of the clips is below the MAF sensor and a little difficult to reach.

You can release the clips with hand pressure or you can slip a flathead screwdriver between the clip and lid and gently pry it off.

Bluboy Comments: Hi
What is the piece of foam inside the airbox for figure 8. Can it be removed if I fit a K&N filter in place of the stock one. It does seem the foam will restrict air flow.
