BMS - B58 BMW Billet Water/Methanol Injection (WMI) Spacer

Plug and play Water/Methanol Injection (WMI) adapter for all B58 BMW motors

Normally you'd replace the factory charge pipe to install a water/methanol kit but in the case of the B58 engine, the factory charge pipe is very sturdy and difficult to remove. So we've 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/methanol applications we suggest dual CM5 nozzles.
