Snow Performance SNO-430 Diesel Stage Boost Cooler Water-Methanol Injection Kit - 2 for Chevy/GMC Duramax

The Snow Performance SNO-430 Diesel Stage 2 Boost Cooler is a complete water-methanol injection system engineered specifically for Chevy/GMC Duramax diesel engines including LBZ, LLY, LMM, LML, and L5P variants. This advanced forced induction system delivers measurable performance gains while significantly reducing exhaust gas temperatures for improved engine longevity and reliability.

Performance Benefits:

• Lower exhaust gas temperatures (EGTs) by 100-300 degrees Fahrenheit
• Increase horsepower by 65+ HP with cleaner, more efficient combustion
• Progressive injection system responds proportionally to boost pressure
• Improved drivability across the entire boost range

Advanced VC-50 Controller Features:

• Integrated 52mm gauge combining boost gauge and water-methanol controller functionality
• 7-color OLED screen (Blue, White, Red, Yellow, Orange, Purple, Green) customizable to match OEM gauges
• Real-time display of boost pressure, injection percentage, and secondary nozzle activation
• Built-in prime button and fault code diagnostics displayed directly on screen
• Adjustable start and full injection points for precise tuning

Complete Kit Includes:

• 300 PSI Extreme Environment sealed UHO (Ultra High Output) pump
• 7-gallon composite tank for extended range
• Progressive VC-50 controller with complete wiring harness
• Dual water-methanol nozzles for proportional injection
• 20 feet of red high-temperature nylon tubing rated to 800 PSI
• Quick-connect fittings for simplified installation
• High-flow check valve and all required mounting hardware

The Stage 2 system utilizes a progressive controller that commands two nozzles to proportionally inject water-methanol based on real-time boost pressure readings. This intelligent delivery system ensures optimal cooling and performance improvements throughout the engine's operating range, making it ideal for daily driven diesel trucks with light to moderate towing applications. All components are 100% methanol-resistant for long-term durability.
