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-BRD

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 reduce exhaust gas temperatures (EGTs) by 100 to 300 degrees, this system promotes a cleaner, cooler running engine while unlocking an increase of 65+ horsepower. Ideal for daily-driven trucks that experience light towing, the kit uses water-methanol injection to optimize combustion and improve overall engine performance throughout the boost range.

By integrating advanced water-methanol injection technology, the Stage 2 Boost Cooler enhances engine efficiency and durability. It is perfect for Cummins owners seeking reliable temperature control and power gains without compromising drivability or engine longevity.

Key Features:

This comprehensive water injection kit offers a range of advanced features designed to maximize cooling and performance benefits for your Dodge Cummins diesel.

• Adjustable Progressive VC-50 Controller with a 52mm gauge combining boost gauge and water-methanol injection control
• Dual water-methanol nozzles that inject proportionally based on boost pressure for precise delivery
• 7-color OLED display (Blue, White, Red, Yellow, Orange, Purple, Green) customizable to match OEM gauges
• 7-gallon tank included for extended range and trip-ready installation
• 300 PSI Extreme Environment sealed UHO pump for reliable, high-pressure operation
• Stainless steel braided lines with 4AN fittings for durability and leak resistance
• High flow solenoid and check valve upgrades for improved fluid flow and system responsiveness
• 100% methanol-resistant components ensuring long-term reliability
• Adjustable start and full points for injection engagement and delivery curve customization

Construction & Design:

The Snow Performance Stage 2 Boost Cooler kit is built with premium materials engineered to withstand harsh diesel engine environments. Stainless steel braided lines provide superior strength and resistance to abrasion, while 4AN fittings ensure secure, leak-free connections. The 7-gallon tank is designed for durability and ample fluid capacity, supporting extended operation without frequent refills.

The VC-50 controller features a vibrant OLED screen housed in a robust gauge body, combining boost monitoring and injection control in a single unit. The dual nozzle setup is optimized for even distribution of the water-methanol mixture, enhancing cooling efficiency across the entire boost range.

Performance & Sound

By injecting a precise mixture of water and methanol into the intake air, the Stage 2 Boost Cooler significantly lowers EGTs by 100 to 300 degrees, reducing thermal stress on engine components. This cooling effect allows for more aggressive tuning and increased horsepower gains of 65+ without compromising engine safety. The system operates quietly and seamlessly, maintaining factory-like drivability while delivering enhanced performance.

Installation & Fitment:

The kit is designed for straightforward installation on Dodge Ram 2500 models from 1994 to 2009 and Ram 3500 models from 1994 to 2007 equipped with the 5.9L Cummins engine. Installation requires routing the supplied stainless steel braided lines and integrating the VC-50 controller with the vehicle’s boost source. The included hardware and fittings simplify the process, making it suitable for professional installation or experienced enthusiasts.
