Product Reviews Review part BM-0400

Dear Sirs,
I am the owner of a BMW R1150RT, this morning I changed my air filter, more of a "maybe it helps" sort of idea. On my drive home I was flabbergasted by the difference. Acceleration response and top end power was really noticeable. I really wish I could explain this in a way your customers could understand. All I can say is try it and you will be REALLY surprised.

Your very happy customer

My BMW 5 series station wagon, 5 speed, would not back up my driveway uphill if the a/c was turned on. Once I installed the K&N filter into the OEM airbox, the car easily backed up the hill.

Thats the difference of running a race with cotton up your nose or not.

Thx K&N for a great product.

I have a 1998 BMW M3 with your K&N Intake system, and I LOVE your intake, the installment was very easy, instructions were clear and very helpful for those not mechanically inclined, and the intake fits well. I can feel the extra power gained from the intake and my gas mileage improved from 18.9 to 20.9 MPG. If you have a BMW M3/328/325, this is the intake to have!
