E21, E30General discussion and technical help for 1975-1991 3 series cars.
new air filter ftw. maybe u should replace that set up with a stock one. Might get less dirty..heh.
as for that wire..not sure.
i kinda agree since it intakes air from behind the headlight. if you get another cone/k&n filter like the one you have, it may be a waste with sucking up that dirt all the time.
altho you can easily clean out a k&n, but i think you would have to do that an awful lot.
At this point I'm kind of thinking of just getting a k&n and cleaning it every week..It isn't too big of a deal since I have alot of time to do tings with...
damit..I knew I shouldn't go to autozone..The guy took the filter to the back and supposedly measured it..and told me what to get from one of the aisles..well..it fits on a 3'' thing..but the adapter for the old one is smaller..I think it's 2.5 idk though cus I can't find something to measure it with..so..now I need to order something off the internet because no store here even carries one under 3'' or the adapter..damit.
UPDATE: I forgot to let you guys know what happened...I ordered a filter and adapter off ebay a while ago..btw..engine bay is much cleaner now..I slowed down a little on the dirt..

An K&N replacement won't get you anything noticable. A K&N cone will make your intake make more noise but probably will not give you any results, maybe with a good exhaust you could get some gain but it would still be relatively small.

Hi I cannot see your pictures.If you are using a K&N filter I would bin it and go back to the original.The original filter is only bringing in air from the front of the car at the headlights (which is cool)where as the K&N is bringing in air from the engine bay(which is hot).
