JHM is proud to be selling this design produced by Hallman. This MBC makes it very easy to set desired boost and is self locking (no more lockdown nuts to worry about). JHM has tested over 5 different MBC designs and this one is by far the best. We are only selling them with the Steel ball since in our testing this is what works best with a B5 S4 (there is a ceramic ball option, but not recommended for the B5 S4).
Includes: Manual Boost Controller - MBC mounting bracket - Hardware -Instructions
