Water/methanol injection is a proven method for forced induction diesel engines equipped with turbochargers or superchargers to effectively lower intake air temperatures and suppress harmful detonation. This allows for increased boost pressure and advanced ignition timing without the need for high-octane fuel, resulting in power gains of up to 20%. AEM's water injection kits utilize robust hardware and offer advanced features that outperform other water/methanol injection systems in the same price range.
