The Snow Performance Stage 3 Diesel Boost Cooler for Chevy/GMC Duramax engines (LBZ, LLY, LMM, LML, L5P) is a water-methanol injection kit that lowers EGTs 100–300°F, cools intake air and can add over 65 HP for heavy towing. Its 2D-mapped controller meters injection using boost and EGT inputs and mounts without invasive dash modifications. A 7 gallon tank is included; Snow says the system leaves no signature on the vehicle warranty.
