Water/Methanol and Nitrous Oxide

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.

This methanol injection system fits the following BMWs:
1998-2006 E46 320i 323i 325i 325xi 330i 330xi 323ci 325ci 330ci M3
