Snow Diesel Stage 3 Boost Cooler – Nylon Line Kit (2004–2025 Silverado / Sierra Duramax) SNO-530
Designed for Chevy and GMC Duramax owners who tow heavy and demand cooler EGTs, the Snow Performance Stage 3 Boost Cooler offers a powerful combination of performance, reliability, and easy installation. Compatible with LBZ, LLY, LMM, LML, and L5P platforms, this water-methanol injection system uses a 2D-mapped controller that adjusts flow based on both boost pressure and exhaust gas temperatures—delivering precision cooling when your engine needs it most.
Expect intake temps to drop by up to 300°F, along with cleaner combustion, reduced emissions, and improved fuel economy. With a gain of 65+ horsepower, this kit helps your truck tackle steep grades with ease while towing.
Installation is clean and non-invasive—the controller mounts directly 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 streamlined unit.
Worried about your warranty? No problem. The Stage 3 system leaves no electronic footprint, keeping your factory coverage intact. Recommended for daily-driven Duramax trucks that regularly tow and face dangerously high EGTs.
