Active Autowerke E46 Methanol Injection System

Active Autowerke E46 Methanol Injection System


Superchargers and turbochargers generate more than just boost. They generate a ton of incremental heat during operation, resulting in a ‘heat-soaked’engine and eroded performance. So their power increase creates its own power decrease problem. Oops.

But an Active Autowerke methanol-water injection system will help chill the intake charge to a cooler temperature – effectively combating the heat soak effect. Additionally, the methanol-water mix increases your engine’s knock limit – thus serving as insurance against unwanted high boost detonation.

The Metahnol-water is precisely delivered and metered by its own electronic module. This module not only monitors the boost pressure within the engine but also controls the delivery flow to match both the engine load and demand as needed.

The large 1.8+ gallon resevoir is well suited for this task. The capacity is there to meet most demands; the trunk mounted location is ideal by being the furthest positin away from both engine and exhaust heat; and its trunk position maximizes the trunk space. It has a rigid mount that's very secure, yet it can be easily detached if needed by its spring loaded quick releases.

If there’s one mod you should be considering for better forced induction performance, this is it.
