Dinan has enigneered a new air box cover that allows  you to run a larger air filter but retain a stock-like appearance. The Dinan 330 intake cover seals better to the lower section ensuring no power-robbing hot air enters the intake. A new lower tube draws air from the brake duct, nearly doubling the volume of cool air entering the engine.

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
