Snow Performance Stage 3 Boost Cooler Water Injection Kit

2007–2020 Dodge Ram 2500 / Dodge Ram 3500 6.7L Cummins Diesel

SNO-510

Overview:

The Snow Performance Stage 3 Boost Cooler Water Injection Kit is engineered specifically for Dodge 6.7L Cummins diesel trucks, including Ram 2500 and Ram 3500 models from 2007 through 2020. Designed for diesel enthusiasts who demand enhanced engine protection and performance during heavy towing, this advanced water-methanol injection system effectively lowers exhaust gas temperatures (EGTs) and intake air temperatures. By maintaining cooler combustion conditions, it helps extend engine life, reduce emissions, and improve fuel economy.

This kit is ideal for owners who frequently tow heavy loads or drive in demanding conditions where high EGTs can compromise engine reliability. The system’s intelligent 2D mapped controller dynamically adjusts injection based on boost pressure and EGT readings, ensuring optimal cooling and power delivery without manual intervention.

Key Features:

The Snow Performance Stage 3 Boost Cooler offers a comprehensive suite of features that enhance diesel engine performance and durability:

• Advanced 2D mapped controller that regulates injection based on boost pressure and exhaust gas temperature for precise cooling
• Significant EGT reduction of 100 to 300 degrees, protecting engine components under heavy load
• Boost gauge, water-methanol controller, and EGT monitor integrated into a single, compact unit
• Non-invasive installation with no drilling or interior modifications required; mounts easily on steering column or dash
• Includes a large 7-gallon tank for extended operation and trip readiness
• Red high-temperature nylon tubing and quick-connect fittings for durability and ease of maintenance
• Dual nozzles and high-flow solenoids for increased injection capacity and performance
• Sealed 300 PSI UHO pump designed for extreme environments
• Compatible with a wide range of Dodge Ram 2500 and 3500 models from 2007 to 2020
• Does not leave a signature on the vehicle, preserving factory warranty coverage

Construction & Design:

The Stage 3 Boost Cooler kit is built with high-quality materials engineered to withstand the rigors of diesel towing and harsh environments. The sealed 300 PSI UHO pump ensures reliable water-methanol delivery under extreme conditions, while the red high-temperature nylon tubing resists heat and abrasion. Quick-connect fittings simplify installation and maintenance, reducing downtime. The controller’s compact design allows for clean mounting on the steering column or dash without requiring additional gauge pods or interior modifications, preserving the truck’s factory aesthetics.

Performance & Sound

By injecting a precise mixture of water and methanol into the intake air stream, this system significantly lowers intake temperatures and exhaust gas temperatures, which in turn reduces engine knock and thermal stress. This cooling effect enables the engine to safely produce more power, delivering an estimated 65+ horsepower increase. The result is smoother, more efficient towing performance with less strain on engine components. The system operates silently, maintaining the truck’s factory sound profile.

Installation & Fitment:

The Snow Performance Stage 3 Boost Cooler kit is designed for straightforward installation on Dodge Ram 2500 and 3500 trucks equipped with the 6.7L Cummins engine from model years 2007 through 2020. Installation requires no drilling or permanent modifications to the vehicle’s interior, as the controller mounts easily on the steering column or dash. The included hardware and quick-connect fittings facilitate a clean, professional setup. The 7-gallon tank provides ample capacity for extended trips and heavy towing scenarios.

What's Included:

• 300 PSI Extreme Environment Sealed UHO Pump
• 7-Gallon Tank Upgrade
• Adjustable Stage 3 Controller with Harness
• 20' Red High-Temperature Nylon Tubing
• Exhaust Gas Temperature (EGT) Probe Assembly
• Boost Line and Required Hardware
• Quick-Connect Fittings
• Snow Performance Decal
• Dual Nozzle Upgrade
• Two High-Flow Solenoid Upgrades
• Snow Performance Hypersonic Water-Methanol Nozzles with High-Flow Check Valve

Ideal For:

This water-methanol injection kit is perfect for Dodge 6.7L Cummins owners who regularly tow heavy loads, drive in hot climates, or seek to maximize engine longevity and performance. It is especially beneficial for daily-driven trucks that experience elevated EGTs during demanding towing conditions. Diesel enthusiasts who want to maintain factory warranty coverage while enhancing power and efficiency will find this system an excellent investment.

Emissions Note

For customers requiring CARB compliance, Snow Performance offers a 50-state legal version of this system under part number SNO-50100, which carries the CARB Executive Order #D-723. The Stage 3 Boost Cooler kit itself does not leave a signature on the vehicle, helping to preserve factory warranty and emissions compliance.

Snow Performance specializes in water‑methanol injection systems designed to reduce intake air temps and support higher boost and timing safely. Popular on forced-induction street/strip builds as well as some tow and diesel applications, Snow kits help manage detonation risk and can enable more consistent power when intake temps and load get aggressive.
