Overview

Show original supplier description
The Snow Performance Stage 3 Boost Cooler is a performance-focused water-methanol injection kit that helps optimize engine efficiency and reduce exhaust gas temperatures (EGTs) by 100-300 degrees. Designed for drivers who tow heavy loads, the system features a 2D mapped controller that precisely manages injection rates based on real-time boost pressure and EGT data. This results in increased horsepower, cleaner internal engine components, and lower emissions. Constructed with premium parts, the kit includes 4AN fittings and a durable stainless steel braided line. The installation is a direct bolt-on, no-drill process that requires light to moderate mechanical skill, with all necessary hardware included in the package. Please note that the fluid tank is sold separately, allowing for installation customization. This kit is specifically engineered for 2007-2026 6.6L Duramax Silverado 3500 HD models. A limited 1-year warranty is included with the purchase.
