AEM V3 Water/Methanol Injection Kit - 1 Gallon, 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 boost-dependent version uses an on-board internal MAP sensor (rated up to 35 PSI) with a molded-in nipple for the boost hose, and ships with a 1-gallon tank with a built-in conductive low-fluid sensor. The progressive controller features large adjustment knobs, a covered status LED and test button for splash resistance, an integrated fuse, and a positive-lock wiring harness with an integrated pump-ground circuit. AEM's "Boost Safe" failsafe output activates on a short, loss of continuity, out-of-range voltage, or low-fluid condition so you can define your own failsafe strategy. Three interchangeable injector nozzles (250, 500 and 1,000 cc/min) cover a wide range of power levels.
