AEM Water/Methanol Injections Systems reduce intake temps and exhaust gas temps and suppress harmful detonation on turbocharged, supercharged, and high compression naturally aspirated racing engines. This reduces knock and allows you to increase boost and timing without using higher octane racing fuel to achieve power gains up to 20%.

Every AEM water methanol injection system comes with robust hardware and delivers more advanced features than comparably priced competitors. The intuitive and ergonomic controller design of our methanol fuel injection systems allows for easy access and adjustment, while the innovative injector design featuring Swirl Generator Technology improves atomization for some of the fastest and least fluid-consumptive inlet temp cooling in the industry.
