Snow Performance Stage 3 Boost Cooler Water-Methanol Injection Kit for 2001-2020 Chevy/GMC Duramax SNO-530

The Snow Performance Stage 3 Boost Cooler is a comprehensive water-methanol injection system engineered specifically for 2001-2020 Chevrolet Silverado/Express and GMC Sierra/Savana trucks equipped with the 6.6L Duramax diesel engine. This kit is designed to significantly lower Exhaust Gas Temperatures (EGTs) by 100°F to 300°F, making it an essential upgrade for diesel owners who frequently tow heavy loads or operate in demanding environments.

At the core of this system is a 2D mapped digital controller that monitors both boost pressure and EGTs to precisely command injection. This dual-input approach ensures the optimal volume of water-methanol is delivered to maintain cool intake temperatures and prevent heat soak. The system also delivers a performance increase of 65+ HP, assisting with heavy towing on steep grades while simultaneously cleaning internal engine components of carbon buildup and reducing emissions by decreasing regeneration cycles.

The kit includes a high-capacity 7-gallon tank for extended range between refills and a non-invasive dash-mounted controller that doubles as a boost gauge and EGT monitor. Designed for maximum reliability, the system features four fault modes to detect clogged or broken lines, pump issues, or solenoid failures. Importantly, this system does not leave a footprint on the factory ECU, keeping your vehicle warranty intact.
