Overview

Already running the Active Autowerke Prima supercharger on your E46 M3? This kit upgrades it to Prima Plus. It adds water-methanol injection and the calibration to run higher boost, and Active Autowerke puts the result at about 465 whp on 93 octane against about 395 whp for Prima.

It was developed with Frank Smith of Tuning Tech FS through many logged dyno runs.

What It Does

Instead of a front-mount intercooler, Prima Plus cools the charge and suppresses knock with water-methanol. A switch brings in 9.0 or 9.5 psi. If the fluid runs low or the engine detects excessive detonation, the system falls back to 6.0 psi on its own to protect the motor, so you keep a safety margin while you enjoy the extra power.

What Is Included

Complete water-methanol system
Trunk-mounted tank with holding base
Methanol-rated pump with internal seals and nozzles
Wiring and switch
