Snow Performance Stage 2 Boost Cooler Chevy/GMC Duramax Diesel Water Injection Kit

The Snow Performance Stage 2 Boost Cooler uses dual water-methanol nozzles, activated progressively by boost pressure, to help keep your Chevy or GMC Duramax diesel running cooler. This kit is designed to lower Exhaust Gas Temperatures (EGTs) by up to 300 degrees and can increase horsepower by over 65. It's a solid option for Duramax owners looking for the benefits of water-methanol injection across their engine's boost range, improving drivability and performance.

At the heart of this system is the VC-50 controller, which also functions as a 52mm gauge. It allows you to precisely tune the engagement and delivery curve of the water-methanol mixture, matching it to your engine's specific needs. The controller features a 7-color OLED screen that displays boost pressure, percentage of injection, secondary nozzle activation, and even fault codes, letting you customize its look to match your dash or monitor key parameters at a glance. The kit includes a high-pressure 300 PSI UHO pump, SP Hypersonic nozzles, a high-flow solenoid upgrade, and a check valve, all made from materials resistant to 100% methanol. The included 7-gallon tank makes it ready for longer trips.

This kit is recommended for daily-driven Chevy and GMC Duramax trucks that handle light towing. It's made in the U.S.A. and comes with red high-temp nylon tubing and quick-connect fittings for a cleaner installation. Please note that this kit is not CARB approved and cannot be shipped to California.
