These plug and play adapters allow you to quickly install a BMS Water/Methanol Injection Kit without drilling/tapping your chargepipe!

Audi S4 Water/Methanol Injection (WMI) Nozzle Adapter

This CNC machined plug and play adapter allows you to mount single or dual BMS Water/Methanol Injection (WMI) nozzles WITHOUT the expense and headache of removing and drilling your factory charge pipe. Shaves a ton of time off the Audi S4 WMI install and best of all is fully reversible. We suggest the BM10 nozzle for most S4 applications. Nozzles not included. Made in the USA.

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.
