The AEM V3 multi-input water/methanol injection kit cools intake charge temperatures and suppresses detonation, letting you safely run more boost and timing. The multi-input controller lets you trigger flow from a 0-5V external MAP sensor, frequency or 0-5V MAF, or injector duty cycle (IDC), making it suitable for high-compression naturally aspirated engines as well as ultra-high-boost setups above 40 PSI. This version ships with a 1.15-gallon tank featuring an anti-starvation reservoir and integral conductive low-fluid sensor, plus a single billet injector. The progressive controller has large adjustment knobs, a covered status LED and test button, an integrated fuse, and a positive-lock wiring harness with integrated pump-ground circuit. "Boost Safe" failsafe output and three interchangeable nozzles (250, 500 and 1,000 cc/min) are included.
