perfect fitment, easy install, better airflow
I've been using K&N filters forever, great airflow and very good filtration. good for the life of the vehicle, just clean it every once and a while, reoil and you're good to go. well worth the money. also worth noting, it gave me better throttle response on my BMW 535i

Fits like a glove - sounds better - BMW 535i
It maybe placebo but the damn car sounds much better. The acceleration too is much better. It could be my imagination but i think this made my car perform better than the OEM filter.
