Impeccable.

It was a great experience buying this air filter online for my E91 320D. Good customer service and it arrived quickly. It was easy to install, it took about a minute to have the old one out and the K&N filter in place. I noticed a difference with the car as soon as I got it out on the road. Realistically it's not a night and day difference, it just feels like the car breathes more easily and revs more freely. It definitely feels more responsive and the hesitation my car had on throttle application is gone too. I highly recommend you get one of these filters for your car.
