Snow Performance Stage 3 EFI 2D Map Progressive Water Injection Kit

This is the Snow Performance Stage 3 Boost Cooler, a progressive water-methanol injection kit designed specifically for EFI and forced induction vehicles. It uses a unique 2D mapping system that adjusts the amount of water-methanol injected based on both your engine's boost pressure and the fuel injector pulse width. This means it delivers precisely the right amount of cooling and octane boost exactly when your engine needs it, extending the injection range beyond simple boost-activated systems.

What you get in this kit is the adjustable Stage 3 controller, which conveniently doubles as a boost gauge and fuel system monitor, so you don't need extra dash real estate. It also includes 1/4" high-temperature nylon line and easy-to-use quick-connect fittings. The system is built around a 300 PSI UHO pump and SP Hypersonic nozzles, and all components are 100% methanol resistant. This setup is proven to lower air inlet temperatures by up to 100 degrees Fahrenheit and increase your fuel's effective octane by 25 points, allowing for more aggressive tuning and maximum horsepower.

Installation is designed to be non-invasive, with the controller mounting easily on your steering column or dash. The kit is made in the U.S.A. and features low-level monitoring to let you know when it's time to refill your tank. Please note that this kit is not CARB approved and cannot be shipped to California.
