The Snow Performance Diesel Stage 3 Boost Cooler Water-Methanol Injection Kit is engineered for turbo diesel owners who require lower exhaust gas temperatures (EGTs) during heavy towing. This system features a 2D mapped controller that precisely manages injection based on both boost pressure and EGTs, optimizing air inlet temperatures and helping to reduce EGTs by 100-300°F. The result is improved engine cleanliness, reduced emissions, and increased fuel efficiency, making it ideal for diesel trucks regularly towing heavy loads. The Stage 3 controller is designed for non-invasive installation, mounting securely to the steering column or dash without any drilling or permanent modification to the interior. It combines the functions of a boost gauge, water-methanol controller, and EGT monitor in a single unit. The system does not leave a traceable signature on the vehicle, preserving your factory warranty. Recommended for daily-driven diesel vehicles that frequently encounter high EGTs under load, the Snow Performance Diesel Stage 3 Boost Cooler is a comprehensive solution for enthusiasts seeking reliability, longevity, and better towing performance.
