The engine intake air filter is a pleated paper element housed inside a plastic box. The paper is designed to be porous to facilitate air flow but prohibits 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 air from entering the engine. If air intake is restricted fuel economy and engine efficiency is reduced; the restriction may reach a point to 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 E60. Replace the air filter once a year or more frequently if you drive in a dusty area. I suggest checking the air filter 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 used in the replacement. 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.

Reigi Comments: Thank you for the post. I replaced the air filter. Started the car. Got a red triangle with exclamation mark on dash board. Went back and checked the filter compartment.Found that I did not reinstall the lid correctly. Reinstalled the lid correctly. But the red triangle is still on. Any idea? My car is a 2010 528i Xdrive

  Followup from the Pelican Staff: Is the hood open when the triangle is ON? If it isn't a check engine light it is a safety warning. - Nick at Pelican Parts
