PRODUCT DESCRIPTION
Snow Performance has combined performance, quality, and ease of installation into this new water-methanol injection kit designed for all turbodiesel owners who demand colder EGT's while towing heavy loads. The Diesel Stage 3 Boost Cooler utilizes a 2D mapped controller that orders injection based off boost pressure and EGT's (exhaust gas temperatures) to keep intake air temperatures extremely cool, 100-300 degree EGT drops, lower emissions, cleaner engine components, and increased fuel economy all while providing 65+ HP to help climb large grades with little effort while towing. A must-have for the diesel enthusiast who cares about the longevity of his heavy towing truck. Non-invasive, the Diesel Stage 3 Boost Cooler controller is designed to mount on the steering column or dash so no drilling/marring of the interior or additional gauge pods are required. It functions as a boost gauge, water-methanol controller, and EGT monitor all in one! Concerned about warranty? The Snow Performance Stage 3 leaves no footprints on the vehicle keeping your diesel truck's warranty intact. Recommended for all daily driver heavy towing diesel vehicles where exhaust gas temperatures (EGT's) reach dangerously high levels.
