Q
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.

A
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.

  1. What ever you do be extra careful NOT to OVER Tighten the air box screws during reassembly! They are threaded into plastic and will strip very easily.
