Normally you’d replace the factory charge pipe to install a water/meth kit but in the case of the B58 engine, the factory charge pipe is very sturdy and difficult to remove. As a result, BMS designed this plug and play adapter for quick installation and removal of BMS dual nozzle water/meth kits without having to replace the factory charge pipe. Simply unscrew three bolts, insert the CNC machined adapter with integrated o-ring in place, and tighten the included longer length bolts, to allow mounting of two meth nozzles with a perfect seal. Includes dual 1/8″ NPT methanol bungs appropriately machined for a clean spray pattern which is critical for proper atomization with the B58 motor. For most B58 water/meth applications, BMS suggest dual CM5 nozzles.
