Snow Performance Stage 2 Boost Cooler Water Injection Kit

1994–2009 Dodge Ram 2500 / 1994–2007 Dodge Ram 3500 5.9L Cummins Diesel

SNO-400

Overview:

The Snow Performance Stage 2 Boost Cooler Water Injection Kit is engineered specifically for Dodge Ram 2500 (1994–2009) and Ram 3500 (1994–2007) trucks equipped with the 5.9L Cummins diesel engine. Designed to lower exhaust gas temperatures (EGTs) by 100 to 300 degrees, this advanced water-methanol injection system enhances engine cooling and increases horsepower by 65+ for cleaner, more efficient performance. Ideal for daily-driven trucks that experience light towing, the Stage 2 kit delivers consistent cooling benefits throughout the boost range, improving drivability and engine longevity.

This kit is perfect for 5.9L Cummins owners seeking a reliable, progressive water injection solution that adapts injection volume based on boost pressure, ensuring optimal cooling and power gains under varying load conditions.

Key Features:

The Stage 2 Boost Cooler combines innovative technology with durable components to maximize performance and reliability:

• Adjustable progressive VC-50 controller with integrated 52mm boost gauge and 7-color OLED display
• Dual water-methanol nozzles that proportionally inject fluid based on boost pressure for precise cooling
• Start and full injection points fully adjustable to match engine requirements and driving conditions
• High-flow solenoid upgrade for improved fluid delivery and responsiveness
• 300 PSI sealed UHO pump designed for extreme environments and 100% methanol resistance
• Large 7-gallon tank included for extended range and trip-ready installation
• Red high-temperature nylon tubing and quick-connect fittings for durability and ease of maintenance
• High-flow check valve to prevent backflow and maintain system integrity
• Snow Performance Hypersonic water-methanol nozzles for optimized atomization and cooling efficiency
• Made in the USA with quality components engineered for long-lasting performance

Construction & Design:

The Snow Performance Stage 2 Boost Cooler kit features robust construction with high-quality materials designed to withstand the rigors of diesel performance applications. The sealed 300 PSI UHO pump is built to operate reliably in extreme environments, while the red high-temp nylon tubing resists heat and chemical degradation from methanol. The dual Hypersonic nozzles provide superior atomization, ensuring efficient water-methanol delivery for maximum cooling effect. The VC-50 controller integrates a boost gauge and injection controller into a compact 52mm gauge housing, featuring a bright OLED screen with customizable colors to match OEM gauges or personal preferences.

Performance & Sound

By injecting water-methanol proportionally throughout the boost range, the Stage 2 Boost Cooler significantly lowers EGTs by 100 to 300 degrees, reducing thermal stress on the engine. This cooling effect allows the engine to safely produce an additional 65+ horsepower, enhancing overall performance without compromising reliability. The system operates quietly with no impact on engine sound, maintaining the factory acoustic profile while delivering improved power and efficiency.

Installation & Fitment:

The kit is designed for straightforward installation on compatible Dodge Ram 2500 and 3500 trucks with the 5.9L Cummins engine. It includes all necessary hardware, fittings, and a large 7-gallon tank for a complete, trip-ready setup. The progressive VC-50 controller allows fine-tuning of injection parameters to match specific engine and driving conditions. Installation requires basic mechanical skills and access to boost lines for sensor integration. The kit fits a broad range of model years and trims, ensuring compatibility across many Dodge Ram diesel trucks.

What's Included:
