Snow Performance SNO-530-BRD Diesel Stage 3 Boost Cooler Water-Methanol Injection Kit for Duramax

The Snow Performance SNO-530-BRD Diesel Stage 3 Boost Cooler is a complete water-methanol injection system designed specifically for Chevy and GMC Duramax diesel engines, including LBZ, LLY, LMM, LML, and L5P variants. This advanced forced induction cooling system safely increases horsepower and torque while reducing exhaust gas temperatures (EGTs) and engine knock.

Key Features:

• Premium stainless steel braided line construction with 4AN fittings for superior durability and heat resistance
• Stage 3 progressive controller automatically adjusts injection based on boost pressure for optimal performance
• High-flow VC-50 injector nozzle delivers precise atomization for maximum cooling efficiency
• Lowers EGTs by up to 200-300°F under load, protecting engine components and extending engine life
• Complete plug-and-play kit includes reservoir tank, mounting hardware, and all necessary installation components
• Allows for increased boost pressure and more aggressive tuning while maintaining safe operating temperatures
• Upgrade from stock intercooler performance without expensive hardware modifications

Water-methanol injection is one of the most effective methods for cooling intake air temperatures on turbocharged diesel engines. The Snow Performance Boost Cooler system injects a fine mist of water-methanol solution into the intake stream, where it evaporates and absorbs heat, resulting in denser air charge, reduced detonation, and significant performance gains. The included progressive controller ensures safe and reliable operation across the entire RPM range.
