i read about it on MINI2 and was interested because I wanted to make my car more responsive but I'm really worried about voiding the warranty. Before I took the plunge I looked on different make websites and saw that they also were raving about the difference it made to their cars, no one had any complaints or had any issues with reliability etc. Then I went back to M2 to see if anyone had developed any problems, which they hadn't. Paul C and paul/martin now have them fitted to their cars and are very happy with the results I know it doesn't look much when you see what you're getting for your £160 but once you've fitted it I guarrantee it'll put a smile on your face. I must add it doesn't increase power it increases responsiveness.
