Just fitted this RAM AIR air filter to my 318i, it fitted like a glove! However, i
am just writing out of curiosity as to wether it was a good move?
It sounds fantastic when in full force, but when the engine is cold the revs are very limited at times and the car in general is incredibly sluggish :(
Any idea's? maybe a new exhaust system or somethin to accompany it may do the trick? Btw this air filter cost me a tenner lol
