Water/Methanol Injection Kits for Boosted and Diesel Engines
A water/methanol kit adds a metered dose of fluid to the air entering your engine. As the fluid evaporates, it pulls heat out of the incoming charge. Cooler, denser air helps resist detonation, so owners of turbocharged and supercharged engines often fit a kit when they raise boost or run more aggressive timing. On diesels, the same cooling effect is used to help manage exhaust gas temperatures under heavy load.
You will find this page under Engine Components › Water/Methanol Injection Kits. We currently have 2 kits in stock, both from AEM. The AEM V3 One Gallon Water/Methanol Injection Kit - Multi Input suits builds where a smaller reservoir fits better. The AEM V2 5 Gallon Diesel Water/Methanol Injection Kit - Multi Input is aimed at diesel trucks that benefit from more fluid capacity between refills.
Engine type: confirm whether your engine calls for a diesel-specific kit.
Reservoir size: a bigger tank means fewer refills but needs more mounting space.
Control inputs: check which signals your vehicle or tune can provide to the controller.
Tuning: plan for your tune to account for the added fluid.
To narrow it down, pick your vehicle to see what fits.
