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

The Snow Performance SNO-530 Diesel Stage 3 Boost Cooler combines performance, quality, and ease of installation in a comprehensive water-methanol injection kit designed specifically for Chevy/GMC Duramax diesel engines (LB7, LBZ, LLY, LMM, LML, and L5P). This advanced system is engineered for diesel enthusiasts who demand cooler exhaust gas temperatures while towing heavy loads and want to maximize the longevity of their truck.

Advanced 2D Mapped Controller Technology:

The Diesel Stage 3 Boost Cooler utilizes a sophisticated 2D mapped controller that commands injection based on both boost pressure and exhaust gas temperatures (EGTs). This dual-input system maintains extremely cold air inlet temperatures while delivering consistent performance gains. The controller functions as a boost gauge, water-methanol controller, and EGT monitor all in one integrated display with a bright LCD screen.

Performance Benefits:

• 100-300°F EGT decreases for safer towing
• 65+ horsepower increase for effortless hill climbing
• Improved fuel economy (1-3 MPG gains)
• Decreased emissions and cleaner engine components
• Cooler air inlet temperatures for consistent power delivery

Complete Kit Includes:

• 2D mapped digital controller with LCD display
• 300 PSI high-output water-methanol pump
• 7-gallon capacity reservoir tank for extended range
• Dual water-methanol nozzles for optimal distribution
• Dual high-flow solenoids for precise injection control
• EGT probe assembly and monitoring system
• Red high-temperature nylon tubing (800 PSI rating, 100% methanol resistant)
• Quick-connect fittings for simplified installation
• Complete wiring harness and mounting hardware

Non-Invasive Installation:

The controller is designed to mount on the steering column or dashboard without drilling or marring the interior, eliminating the need for additional gauge pods. The system does not leave a signature on the vehicle, helping maintain your diesel truck's warranty intact. Features adjustable progressive boost and EGT-activated water-methanol engagement for customized performance.

100% Methanol Resistant Components:

This kit features premium materials including stainless steel components, EPDM seals, and hard anodizing to ensure years of reliable operation even with 100% methanol mixtures. The proprietary ACU-SEAL compression fittings guarantee leak-free operation.

Recommended for all daily-driven Chevy/GMC Duramax owners who engage in heavy towing where EGTs become dangerously high. Compatible with 2001-2022 GM 6.6L Duramax diesel engines including LB7, LBZ, LLY, LMM, LML, and L5P engine codes. A typical 3/4 or 1-ton pickup will travel approximately 500 miles towing heavy loads or 1000 miles empty before requiring reservoir refill.
