AEM V3 Water/Methanol Injection Kit - Tank-Less, Boost-Dependent

The AEM V3 water/methanol injection kit cools intake charge temperatures and suppresses detonation on forced-induction gasoline engines, letting you safely run more boost and timing. This tank-less, boost-dependent version uses an on-board internal MAP sensor (rated up to 35 PSI) with a barbed fitting for the boost line, and ships without a reservoir so you can integrate a custom or third-party tank. Interchangeable injector nozzles cover a range of power levels, and an LED status light reports system state. A fitting for a third-party tank is included.
