Snow Performance Stg 3 Boost Cooler DI 2D MAP Prog. Water Injection Kit (SS Brded Line/4AN) w/o Tank

Snow Performance is well-known for their water-methanol injection systems, and their Stage 3 Boost Cooler takes that expertise and applies it to modern direct-injected, forced-induction vehicles. This kit is designed to bring advanced 2D mapped water-methanol injection to your turbocharged or supercharged car, ensuring you get the right amount of spray precisely when your engine needs it most. By using both boost pressure and fuel pressure sensors, the system creates a dynamic injection map that can extend beyond specific boost thresholds, giving you more control and a wider operating range.

What sets this Stage 3 controller apart is its integrated functionality. It mounts conveniently on your steering column or dash, serving as a boost gauge, the water-methanol controller, and a fuel system monitor all in one unit, so you don't need to buy extra gauges. This setup is proven to significantly reduce air inlet temperatures, by as much as 100 degrees Fahrenheit, and can increase your fuel's effective octane rating by up to 25 points. This combination of cooler intake air and higher octane allows for more aggressive tuning and maximum horsepower gains. The kit includes the adjustable Stage 3 controller, 4AN fittings, and stainless steel braided lines for a clean and durable installation of your pump and tank in the engine bay.

This kit does not include a tank, so you'll need to source that separately. Please note that this system is not CARB approved and cannot be shipped to California. It's important to check local regulations regarding water-methanol injection systems.
