Ramp up your MPG's, lower your EGT's, and increase power with the only Water-Methanol Injection system designed and proven to increase fuel economy. The Snow Performance Stage 3 Injection System is just that, all while offering you more horsepower and torque. Act now and start saving at the pump by adding this triple-threat system for a gain of 1-3 miles per gallon!

Snow Performance has combined performance, quality, and ease of installation in this water-methanol injection kit designed for all Chevy Duramax owners who demand colder EGTs while towing heavy loads. The Diesel Stage 3 Boost Cooler utilizes a 2D mapped controller that commands injection based on boost pressure and EGTs (exhaust gas temperatures) to maintain extremely cold air inlet temperatures, 100-300 EGT decreases, decreased emissions, cleaner engine components, and increased fuel economy, all while giving 65+ horsepower to help pull large hills with easy effort while towing.

A must have for the diesel enthusiast that is concerned about the longevity of his truck that sees heavy towing. None invasive, the Diesel Stage 3 Boost Cooler controller is designed to mount on the steering column or the dash so no drilling/marring of the interior needs to take place or additional gauge pods need to be purchased. Functions as a boost gauge, water-meth controller and EGT monitor all in one! Concerned about warranty? The Snow Performance Stage 3 does not leave a signature on the vehicle leaving your diesel truck with its warranty intact. 7 Gal Tank included for trip ready installation.

Aún no los eh probado pero tienen muy buena pinta y en las primeras impresiones se sienten muy bien en los pies además que me encantan que sean de un modelo que no necesitan estar teniendo que atar los cordones

Poor quality control… Received a used pair
Size: 12, Color: Birch Beige/Farro/Ivory, Size: 12, Color: Birch Beige/Farro/Ivory
The shoes that were delivered showed signs of wear. Not sure if this was a used pair or a display pair but this should have been caught from the beginning. I would normally return them, but will be out of the country for the next month and don’t have the time. Unacceptable quality control from the official cole haan store front.
