In Reply to: Drivers Compartment Air Filter E46 posted by LK on December 29, 1998 at 05:12:17:
: Does the E46 have a filter that filters outside air before it it enters the drivers compartment? If so can it be replaced easily?
It does indeed. It is an activated charcoal + microfiber filter and it is located directly on the firewall (under the hood). It is easily replaced using no tools. There are 3 plastic thumb screws holding the cover on to the filter compartment. Once the cover is off, you simply lift the filter out and replace the keyed new filter (it will only fit in one orientation) back in the compartment. Replace the cover and you are done. 2 minute job (if that!)
