Snow Performance Stg 2 Boost Cooler F/I Prog. Water Injection Kit (SS Braided Line 4AN Fittings)

If you're running a supercharged or turbocharged vehicle and looking to squeeze more power out of it safely, this Stage 2 Boost Cooler water-methanol injection kit from Snow Performance is a solid option. It's designed to help your engine run cooler, which means you can safely increase boost pressure and timing for more horsepower, all while using pump gas. This system is particularly useful for boosted engines that tend to run hot, as it can lower intake air temperatures by up to 100 degrees Fahrenheit.

What sets this kit apart is the progressive VC-50 controller. It's not just a simple on/off switch; it proportionally injects more or less water-methanol mixture based on your actual boost pressure. You can adjust the engagement point and the delivery curve to perfectly match your engine's needs, ensuring you get the right amount of cooling and octane boost across a wide range of operation. This means improved drivability and consistent performance gains. The controller itself also functions as a 52mm gauge, featuring a 7-color OLED screen that displays boost pressure, injection percentage, low fluid level warnings, and even fault codes, allowing you to keep an eye on critical engine parameters.

This particular kit comes with stainless steel braided lines and 4AN fittings, making it suitable for mounting the pump and tank in the engine bay. It's built with a 300 PSI UHO pump and Hypersonic nozzles, and all components are 100% methanol resistant. The kit also includes low-level monitoring and a high-flow check valve to ensure reliable operation. Remember, this kit is made in the U.S.A. and is not CARB approved, so it cannot be shipped to California. For trunk mount options, you'll need to look at different part numbers.
