Every 10,000 miles or so, you should change the two engine air filters in your BMW E65. 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 you less than an hour. Remember to clean out the air boxes before you install the new filters, as you do not want to put a clean air filter in a dirty air box.

The procedures are the same for both airboxes.

There are two engine air filters on the E65 located in the front corners of the engine compartment (red arrows).

There are two hose clamps and a hose connecting the airbox lid to the intake system.

Next, unclip the two clips closest to the fender (red arrows).

Lift the lid up and towards the center of the engine.

Lift the lid up and towards the center of the engine. The lid will slide out of the slots, and the hose will slide off the intake.

Pull the air filter from the airbox.

Pull the air filter from the airbox. Use care. If your filter is really dirty you do not want to get all the dust and dirt all over the engine. Pay attention to the orientation of the filter. Make sure to install the new one in the same direction.

Clean out the bottom of the airbox with a vacuum and clean rag; there is no point in putting a clean air filter in a dirty airbox.
