Einleitung
Regular maintenance on a 2000-2006 (E46) BMW M3 is very important, but going to a dealership or certified technician can be expensive. So why not do some of it yourself? Replacing the air filter in the engine, for instance, is a simple, not too invasive, and low-risk job for anyone looking to save the $100+ that a dealer might charge to do the job.
Note: This guide may not apply to the installation of an aftermarket air filter.
