The filter is awesome. I could feel the diffrence right after I put it on and will definitely buy another one for my other car.

I have been purchasing K&N filters for my cars for the last 24 yrs. and have never been disappointed. They perform as advertised and are reasonably priced. Buying them online is very easy and convenient and delivered on time. As a matter of fact, as soon as I finish this message I am ordering one for my new Jeep.

Bien, le moteur de ma BMW série 3 GT à l'air de mieux respirer.

Very simple to fit, literally 2 minutes. Makes a nice sucking induction noise on wide open throttle. Good purchase.
