Review on 57A 6037 Cold Air Induction System by Sam Bauer

I installed this system on my 2009 MINI Cooper S Clubman. The only change I had to make was the flow sensor, or MAP, which is located on the end of the factory airbox. According to K&N, this system is for non-US engines but legal for street use in some states. They provide a list of states. What is required is to unscrew the sensor from the factory airbox and reinstall it into the intake hose. When installing a new Apollo filter housing on an engine you will need to cut about 2 inches from the sensor side of the supplied rubber elbow then the new system will fit all supplied parts according to the instructions provided. Most of it is gone, the car is faster and the fuel consumption increases slightly when you can take your foot off the pedal.
