Snow Performance Stg 1 Boost Cooler F/I Water Injection Kit (Incl. SS Braided Line and 4AN Fittings)

If you're running a supercharged or turbocharged engine and want to squeeze more power out of your pump gas, a water-methanol injection system like this Stage 1 Boost Cooler is a solid option. It works by injecting a mix of water and methanol into your intake charge, which cools things down and raises your fuel's effective octane by up to 25 points. This helps prevent detonation, allowing your engine to run more aggressively and make more power, typically an extra 30-70 horsepower on forced induction setups.

This kit is designed for low to medium boost applications, generally between 1 and 15 PSI, and is particularly well-suited for vehicles with positive displacement superchargers. The system activates automatically via an adjustable boost switch, injecting the water-methanol mix only when you're making boost and shutting off when boost drops. The kit includes stainless steel braided lines and 4AN fittings, making it easier to route the pump and tank within the engine bay. It's also built with a 300 PSI pump and specialized nozzles for effective atomization.

This kit is made in the U.S.A. and is 100% methanol resistant. While it's not CARB approved and cannot be shipped to California, it's a popular choice for enthusiasts looking to safely increase power on pump gas.
