Replace Air Filter, BMW 325i, 328i, 330i, Etc – E90, E91, E92, E93
This answer is applicable for many BMWs in addition to the one listed below.
I own a 2006 BMW 325I E-90 and I would like to replace the air filter. I cannot figure out how to remove the old one. Any help (or links) would be appreciated.
On all E90/91/92/93 models (3-series 06-current), except the M3 and the turbo models, the air filter box must be removed from the vehicle in order to remove the air filter. The procedure is covered (with photos) in the Bentley repair manual for the E90/91/92/93 chassis. Here are the basic steps:
* Disconnect the engine air duct from the box, at the rear of the box.
* Disconnect the inlet duct from the front of the box.
* Remove the two mounting bolts on the driver’s side of the box.
* Lift the box out.
* Remove the five screws securing the two halves of the box together and separate the box halves.
* Remove the filter.
