This latest Ask MF comes from Steve:

>As a Stage 1 JCW owner, am I able to purchase the factory JCW air mass sensor, air filter, inlet tube, exhaust and downpipe and ECU mapping? My guess is that it would cost an arm and a leg but curious at the performance benefit. My guess is that it would be pretty close to output of the factory JCW. Can you also enlighten us on whether or not warantee would be affected? Does the MINI dealers treat the factory JCW like the GP where only those owners are able to get those parts?

It’s a great series of questions and honestly we don’t know the answer because we haven’t tried. However we’re guessing a few readers have either looked into it or even gone down this path already. Do with that we’ll turn it over to them. Feel free to sound off in the comment section below.
