Noticeable improvement in throttle response in conjunction with Berger JB4. The X1 doesn't feel as much like a grocery getter and is a lot more fun to drive. Thanks K&N for making an affordable solution for better airflow.

Excellent product. Replaced the standard air filter in my Mini Cooper SD and immediately noticed a marked improvement in terms of 'breathing'. I have been fitting K&N filters to all my cars since the late 1980s and highly recommend these filters to anyone.

The K&N replacement air filter arrived on time and certainly has helped the accelerator response. It has also slightly improved the sound of the engine.

Love the product! The car drives better with better response accross the Rev range and improved mpg. The only disappointment is that it's no louder than stock and maybe a little less turbo noise. Had a panel filter on my mini gp2 and that sounded much better then stock. I but if your not bothered about noise, then I really recommend this filter for your mini. :)
