Water Meth Kits

Water Methanol Injection Kits

Water methanol injection kits spray a fine mist of water and methanol into the intake charge, dramatically lowering intake air temperatures and increasing the effective octane rating of the fuel. Water-meth injection allows more aggressive timing and boost on turbocharged and supercharged engines while providing a safety margin against detonation.

OneFastShop carries water methanol injection kits including complete single and multi-nozzle kits, progressive and on/off injection systems, trunk-mount and engine-bay-mount reservoirs, and application-specific water-meth kits for popular turbocharged and supercharged platforms.

Every water-meth kit at OneFastShop ships brand-new with manufacturer warranty coverage. Whether you're adding detonation protection to a big-turbo build, lowering intake temps on a supercharged V8, or stacking water-meth with E85 for maximum power, OneFastShop has the kit.
