Water Injection System - AEM

$ 424.95

Water/methanol injection for gas engines is a proven means for effectively reducing engine inlet air temperatures and suppressing harmful detonation on forced induction and high performance naturally aspirated race engines. This allows racers to reliably increase boost and advance ignition timing without using high-octane racing fuel for power gains of up to 20 Percent. AEM’s Water/Methanol Injection Systems utilize the most robust hardware combined with more advanced features than any other comparably priced water/methanol system. The on-demand progressive controller in AEM’s Boost Dependent Water/Methanol Injection kit bases injection flow on manifold pressure using an on-board MAP sensor (up to 35 PSI of boost) to ensure the proper amount of water/methanol injection at all points along an engine’s power curve. The new controller design features large, turn-resistant knobs and larger numbering to easily set accurate start and full activation points, with covered status LED and test buttons for added splash resistance. A plug is integrated into the controller housing for mating to the redesigned wiring harness’s positive-lock connector. The Boost Dependent controller housing has a molded-in, barbed nipple to accept a boost hose and a wiring legend on the back, integrated fuse and molded mounting tabs.
