Snow Performance Stage 3 Boost Cooler Water Injection Kit

2007–2017 Dodge Ram 2500/3500 5.9L & 6.7L Diesel

Part #: SNO-510-BRD-T

Overview

The Snow Performance Stage 3 Boost Cooler Water Injection Kit is engineered specifically for Dodge Ram 2500 and 3500 trucks equipped with 5.9L and 6.7L diesel engines from 2007 through 2017. 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 injecting a precise mixture of water and methanol, it helps maintain cooler combustion conditions, resulting in cleaner engine components, reduced emissions, and improved fuel economy.

This kit is ideal for owners who regularly tow heavy loads and want to extend the longevity of their diesel engine while gaining additional power. The system’s intelligent 2D mapped controller adjusts injection based on boost pressure and EGT readings, ensuring optimal cooling and performance without compromising drivability or factory warranty.

Key Features

The Stage 3 Boost Cooler combines innovative technology with user-friendly design to deliver reliable performance gains and engine protection:

• 2D mapped controller that modulates injection based on boost pressure and exhaust gas temperature for precise cooling
• Reduces EGTs by 100 to 300 degrees, helping prevent dangerous temperature spikes during heavy towing
• Decreases intake air temperature for denser combustion and improved power output
• Provides an estimated 65+ horsepower increase under load for easier hill climbing and towing
• Functions as a boost gauge, water-methanol injection controller, and EGT monitor in one integrated unit
• Non-invasive installation with no drilling required; mounts easily on steering column or dashboard
• Includes a 7-gallon tank for extended range and trip-ready setup
• Does not leave a signature on the vehicle, preserving factory warranty coverage
• Compatible with Dodge Ram 2500 and 3500 models from 2007 to 2017 with 5.9L or 6.7L diesel engines

Construction & Design

Snow Performance’s Stage 3 Boost Cooler kit features high-quality stainless steel braided lines that ensure durability and resistance to abrasion and heat. The water-methanol injection components are engineered for long-lasting reliability under demanding conditions. The compact controller unit is designed for easy mounting without interior modifications, preserving the factory look and feel of your truck’s cabin. The included 7-gallon tank is constructed to withstand road vibrations and harsh environments, providing ample capacity for extended towing trips.

Performance & Sound

By injecting a water-methanol mixture into the intake air stream, this system significantly lowers combustion temperatures, which reduces the risk of engine knock and thermal stress. The result is a cleaner, more efficient burn that translates into increased horsepower—typically 65+ HP—especially noticeable when towing heavy loads or climbing steep grades. Additionally, the cooler combustion process helps maintain quieter engine operation by reducing detonation and harsh exhaust tones.

Installation & Fitment

The Snow Performance Stage 3 Boost Cooler kit is designed for straightforward installation on Dodge Ram 2500 and 3500 trucks with 5.9L or 6.7L diesel engines from 2007 to 2017. The system mounts easily without the need for drilling or permanent modifications, utilizing a steering column or dashboard mount for the controller. The included stainless steel braided lines connect seamlessly to the intake system, and the 7-gallon tank can be securely installed in the bed or frame area. This non-invasive design ensures a clean installation that maintains the vehicle’s factory appearance and warranty.

What's Included

• Stage 3 Boost Cooler 2D mapped controller (boost gauge, injection controller, and EGT monitor)
• Stainless steel braided water-methanol injection lines
• 7-gallon water-methanol reservoir tank
• All necessary fittings, wiring harnesses, and mounting hardware
• Comprehensive installation instructions

Ideal For

This kit is perfect for Dodge Ram 2500 and 3500 diesel owners who frequently tow heavy trailers or haul large payloads and want to protect their engine from excessive heat. It is especially beneficial for daily-driven trucks that experience high EGTs under load, helping to extend engine life, improve fuel efficiency, and boost power output. Diesel enthusiasts looking for a reliable, warranty-safe water-methanol injection solution will find this system an excellent upgrade.

Emissions Note

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

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.
