Great air filter for my 11 BMW 328. Wish it added more power on the dyno though.

Thank you for a good high quality product that fits just as good as the original equipment. I have installed K&N air filters on all of my vehicles and I am very satisfied with the outcome. I have proven to myself that there is decreased fuel consumption by using K&N filters.

This is a really good part to have. It actually added some horsepower and torque, you can feel it. You can also hear the difference in exhuast. I have straight pipes on my bimmer and this just made it backfire more. Sounds so good.
