im kinda hesitant about this AFE intake, my friend had it on his 2002 m3 and it basically messed with his mass air sensor, made the check engine light go on and he felt a significant loss in power causin him to replace intakes.


He ended up replacing it with a K&N cold air intake and after he installed the K&N, his m3 was back to normal had actually better power increase and the check engine light shut off.

Im not tryin to say the AFE product is bad in anyway shape or form, im just a bit hesitant about their intakes. We also do not have m3's we have X5's, so im just a bit hesitant.

Some guys that do have this intake already... any check engine lights or any power loss and or a hesitant type of power response as if its almost like the car stutters at low speed from 5-10mph?
