Snow Diesel Stage 3 Boost Cooler – Braided Line Kit (2004–2025 Silverado / Sierra Duramax) SNO-530-BRD
Built for Chevy and GMC Duramax owners who tow heavy and demand cooler EGTs, the Snow Performance Stage 3 Boost Cooler delivers a powerful combination of performance, reliability, and easy installation. Compatible with LBZ, LLY, LMM, LML, and L5P engines, this water-methanol injection system uses a 2D-mapped controller that adjusts injection based on both boost pressure and exhaust gas temperatures—ensuring precise cooling when your engine needs it most.
Expect a dramatic drop in intake air temps (up to 300°F), improved fuel economy, cleaner combustion, and a gain of 65+ horsepower—perfect for climbing steep grades with confidence. The controller mounts cleanly to the dash or steering column, eliminating the need for drilling or extra gauge pods. It functions as a boost gauge, water-meth controller, and EGT monitor in one compact unit.
Concerned about warranty coverage? No worries—this system leaves no electronic trace on your vehicle, keeping your factory warranty intact. The included 7-gallon tank makes installation trip-ready right out of the box.
Recommended for daily-driven Duramax trucks that regularly tow and face dangerously high EGTs. Need a CARB-compliant version? Check out part #SNO-50100, certified 50-state legal under C.A.R.B. EO #D-723.
