FS: Sprint Booster V1, manual For sale is a used Sprint Booster for a manual MINI. Its a gen 1 version that is not adjustable. I had this on my 06 JCW for a few years and it works great. Significantly improves throttle response and is quick to respond to your foot. I've decided I prefer the more mellow nature of the stock interface. This only take about 10 minutes to install, if that.
