I've had this filter in my 2003 BMW 525i for about 2 months now. I did notice more power while accelerating. This filter has also improved my gas mileage slightly. The installation was fairly simple. I think K&N should make a video on the installation to make things easier, but I got by with their instructions. Overall, this is a great product. It's an easy bolt-on part that boosts power and fuel efficiency. I reccomend K&N filters to everyone I know. If your are looking for something fairly cheap and easy to install, this intake is a real bang for your buck, and is for you.
