The engine intake air filter is a pleated paper element housed inside a plastic box. The paper is designed to be porous to air flow but prohibit dust particles and grit from entering the engine intake ports. With time and depending on local conditions, the filter element becomes clogged and may eventually slow down or even altogether stop sufficient intake air from entering the engine. If the air intake is restricted, fuel economy and engine efficiency is reduced; the restriction may reach a point at which the engine does not run at all.

In this article, I'll go over the steps involved with replacing the air filter on the BMW F30 with an N20 engine. Replacing on other engines is similar.

Replace air filter once a year or more frequently if you drive in a dusty area. I suggest checking each time you change your engine oil, assuming you are changing your oil every 5,000 miles. It's easy to remove to inspect it and replacing it early will help you maintain your maximum fuel economy.

Keep in mind that when your car was serviced before, parts may have been replaced with different size fasteners. The sizes of the nuts and bolts we give may be different from what you have, so be prepared with different size sockets and wrenches.

Protect your eyes, hands and body from fluids, dust and debris while working on your vehicle. If working with the electrical system, disconnect the battery before beginning. Always catch fluids in appropriate containers and properly dispose of any fluid waste. Recycle parts, packaging and fluids when possible. Never work on your vehicle if you feel the task is beyond your ability.

Our vehicle may vary slightly from yours as models do change and evolve as they grow older. If something seems different, let us know and share your info to help other users.

The air filter is located in the air filter housing (red arrow), it is mounted in the right side of the engine compartment inside the intake air housing.

Pull the air filter out and replace it.

Pull the air filter out and replace it. I suggest cleaning any debris from the air filter housing once the filter is removed. Leaves and dirt can gather inside the housing and possibly plug the air filter. Install the new air filter; be sure it is properly seated. Then reassemble housing.
