Snow Performance Stg 3 Boost Cooler DI 2D MAP Prog. Water Injection Kit (SS Braided Line & 4AN)

This kit from Snow Performance brings advanced 2D mapped water-methanol injection to your direct-injected, forced-induction vehicle. What you get in this specific package is the adjustable Stage 3 water-meth controller, which also functions as a boost gauge and fuel system monitor, along with 4AN fittings and stainless steel braided lines. This setup is designed to help you mount your pump and tank in the engine bay, offering a clean and integrated look.

The Stage 3 system is pretty clever because it creates a 2D injection map that responds to both boost pressure and fuel pressure sensors. This means it delivers precisely the right amount of water-methanol mixture exactly when your engine needs it most, extending the injection curve beyond just specific boost points for better overall control. This advanced mapping is proven to significantly reduce intake air temperatures, by up to 100 degrees Fahrenheit, and effectively raises your fuel's octane rating by about 25 points. This combination allows for maximum horsepower gains and superior engine cooling, especially important when you're pushing your turbocharged or supercharged engine hard.

Built with a 300 PSI UHO pump and Hypersonic nozzles, this kit is made to handle 100% methanol. It also includes a high-flow check valve to ensure proper flow and a low-level monitoring system to keep you informed. Everything is made in the U.S.A. Keep in mind that this kit is not CARB approved and cannot be shipped to California. If you're looking to mount your tank in the trunk, you'll want to check out different part numbers.
