Water meth is a great way to get maximum performance out of your forced induction BMW. With all of the new turbo BMWs on the road, water meth injects a mixture of the two into your vehicle's intake to increase octane and reduce detonation. If you're looking to get the most out of your turbo BMW, check out the water meth kits we offer at Turner Motorsport.

Turbo vehicles often suffer from heat soak - methanol injection systems help cool the intake charge, and increases your engine’s knock limit – giving you a failsafe against high boost detonation. Active Autowerke's methanol-water is precisely delivered and metered by its own electronic module, which measures boost pressure within the engine and controls the delivery flow to match both the engine load and demand as needed.

  • The large 1.8+ gallon reservoir
  • Rigid mount can be easily detached if needed by its spring loaded quick releases.
  • For offroad use only.
  • Does not include any fluid.

With CNC machined serviceable/cleanable nozzle inserts for precise fluid metering. Choose single or dual nozzles and match the flow rate to your power needs! ​Water/Methanol Injection (WMI) nozzles are determined by the intended power and how many bungs your charge pipe has. These nozzles are 1/8” NPT and screw in to bungs included on most aftermarket charge pipes. BMS "super atomizing" nozzles are designed and manufactured by BMS and are known for their great atomization and flow characteristics. The number on the methanol injection nozzle represents the approximate gallons per hour of fluid when at full flow. Generally speaking running two smaller nozzles is preferred to one larger nozzle for an equal flow to improve fluid atomization and distribution.
