B58 Billet Water Injection Spacer - Gen1 B58 (B58A)

Plug-and-play water injection adapter for all Gen1 B58 BMW motors 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. 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/meth applications we suggest dual CM5 nozzles. What's Included: (Gen 1 B58) (1) Billet Spacer (3) M6x1.0x50mm bolts (2) 1/8 NPT bung plugs (2) 90º nozzle adapters
