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

The CSL Airbox is one of the most demanded improvements among BMW M3 E46 enthusiasts. That is both for performance gain and for the sound it brings to the car. On the other hand, it is a laborious, time-consuming, and expensive modification. For those who are looking for a similar sound to the CSL airbox but are not looking for HP gain, we have developed the Karbonius OEM Style S54 airbox. It is a simplified version of the CSL airbox, that, apart from a louder sound from the engine (+12 dB compared to plastic OEM), gives an awesome appearance and allows for easy installation using the stock elbow and MAF sensor. No need to remap! Regarding power increase, we got +4HP in a recent dyno test compared with the OEM airbox. Not really significant considering that dynos can have a 2% margin error. In conclusion, and pending new tests in the future, we can say no significant power increase and no HP loss. NOTES: Need to install with CSL Crankcase breather hose -- BMW # 11157833649) In SMG version, need to install a Genuine BMW CSL SMG Expansion Tank -- BMW # 21532282549 Fitment: BMW M3 E46 BMW Z4 M

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.
