The AEM V3 multi-input water/methanol injection kit cools intake charge temperatures and suppresses detonation on forced-induction gasoline engines, letting you safely run more boost and timing for power gains of up to 20% without high-octane race fuel. The multi-input controller triggers flow from a 0-5V external MAP sensor, frequency or 0-5V MAF, or injector duty cycle (IDC), covering high-compression naturally aspirated engines and ultra-high-boost setups above 40 PSI. This heavy-duty version ships with a 5-gallon tank and two injectors for high-output gasoline applications. A recirculation-style pump, billet injectors with integral check valves, "Boost Safe" failsafe output and a positive-lock harness with integrated pump-ground circuit are included, along with 20 ft of high-pressure nylon tubing.
