Snow Performance 07-17 Dodge 6.7L Stg 3 Boost Cooler Water Inj. Kit (SS Braided Line/4AN) w/o Tank

If you're looking to keep your 2007-2017 Dodge 6.7L Cummins running cooler and cleaner, especially when you're towing heavy loads, this Stage 3 Boost Cooler water-methanol injection kit from Snow Performance is a solid option. It's designed to inject a water-methanol mixture into your intake charge, which significantly lowers exhaust gas temperatures (EGTs) and can even help reduce emissions and keep engine components cleaner. This can also lead to improved fuel economy and a noticeable boost in horsepower, giving you more power to handle those big hills while towing.

What sets this Stage 3 kit apart is its advanced 2D mapped controller. It doesn't just inject based on a timer; it actively monitors your boost pressure and EGTs, adjusting the injection rate precisely to maintain those cold intake air temperatures. This means you get consistent performance and protection, with EGTs potentially dropping by 100-300 degrees. The controller itself is designed to be non-invasive, mounting conveniently on your steering column or dash without needing to drill into your interior or buy extra gauge pods. It even functions as a boost gauge and EGT monitor all in one unit, giving you valuable real-time information.

The kit features stainless steel braided lines and 4AN fittings, which are well-built for durability and a clean installation. While this specific kit does not include a tank, it's recommended for daily driven Cummins trucks that frequently tow heavy loads and are concerned about high EGTs and engine longevity. Snow Performance has designed this system to be non-invasive, meaning it generally leaves your truck's factory warranty intact. For those in California or states requiring CARB approval, a different part number is available.
