annoying airbox stuff

[London]

Only difference I noticed with the K&N was on startup the car ran smoother. Once everything was warmed up I never noticed a difference. With the stock airbox the idle seems to fall a little when the revs fall from say 2500, it'll drop then come back up when the engine is cold. But thats probably a vacuum leak somewhere...

AFMs aren't sensitive to oiled filters, MAFs are - and only if you use way too much oil on them.

Oh I thought it was the other way around
