Snow Performance Chevy/GMC Duramax Diesel Stage 3 Boost Cooler Water Injection Kit w/o Tank

Snow Performance is well-known for creating effective water-methanol injection systems that help diesel owners get more out of their trucks. This Stage 3 Boost Cooler kit is specifically designed for Chevy and GMC Duramax diesel engines, offering a way to manage exhaust gas temperatures (EGTs) and improve overall performance, especially when towing heavy loads. It's a solid option for owners concerned about the long-term health of their engine under demanding conditions.

What sets this kit apart is its advanced 2D mapped controller. It intelligently adjusts water-methanol injection based on both boost pressure and EGT readings, ensuring your intake air stays significantly cooler. This not only helps decrease emissions and keep engine components cleaner but can also lead to improved fuel economy. You can expect a notable decrease in EGTs, often between 100-300 degrees, and a potential gain of over 65 horsepower, making those steep grades much more manageable. The controller itself is designed for easy, non-invasive mounting on your steering column or dash, functioning as a boost gauge, EGT monitor, and the water-methanol controller all in one unit, so you won't need extra gauges or to drill into your interior.

This kit is recommended for daily-driven Duramax trucks that frequently handle heavy towing where high EGTs are a concern. The system uses high-temperature nylon tubing and quick-connect fittings for a straightforward installation. While this specific kit does not include a tank, it's designed to integrate seamlessly with a separate tank for trip-ready operation. Snow Performance systems are known for not leaving a signature on the vehicle, which can help keep your factory warranty intact.
