Garcia, Surrey, United Kingdom
Easy to fit, easy to clean, even the engine sound is a bit better, and the petrol consumption is less than with the original filter. Highly recommended.
Rodney Edwards, North Carolina
Popped this baby in and immediately could hear the supercharger whinning a lot more and can feel more power. It's helped so much, I can climb large hills in 5th, where I used to have to change to 4th. Excellent quality product that pays for itself.
Bob Phillips, Indianapolis, Indiana
I installed the new K&N filter in my 2006 Mini Cooper S. I feel comfortable knowing I have the best air filter in the world in my car. Thanks K&N.
