"I like the intake very much. Car seems to run a little better with it. Only problem that I have with it is that it stated that it would connect to my cars intake with NO problems. The Mass Air Flow pipe on the BMW did not fit into the AFE tubing. SO I had to sand down the inside of the AFE tubing and I was not very happy I had to do that. Like the product just disappointed with the fact that it didn't just connect right up to the car." —Scott L from Cornwall, NY bought an aFe Cold Air Intakes for a 2001 BMW 3-Series, 330i, 3.0L 6 cyl. engine.
