Snow Performance Stage 2 Boost Cooler Chevy/GMC Duramax Diesel Water Injection Kit (SNO-430)

Description

The Snow Performance Stage 2 Boost Cooler is engineered for Chevy/GMC Duramax Diesel engines (LBZ, LLY, LMM, LML, L5P) to reduce exhaust gas temperatures (EGTs) by 100-300 degrees and increase horsepower by 65+ through advanced water-methanol injection across the boost range.

This system features a progressive VC-50 controller (52mm gauge) that manages dual water-methanol nozzles with boost-proportional injection, providing precise cooling and performance improvements tailored to engine demands. The VC-50 combines a boost gauge with water-methanol control, offering a 7-color OLED display for boost, injection percentage, secondary nozzle activation, prime function, and fault codes. The injection curve and engagement points are fully adjustable for optimized drivability. A 7-gallon tank is included, making the kit suited for daily-driven Duramax trucks with light towing.
