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.

Nice-looking shoes
Size: 7.5, Color: B-black
I really like the look of these shoes. They can be worn for more casual look or more dressy look. When I first tried them on I considered returning them because they were a little tight in the width. I wore them for the first time today. After only 2-3 hours of wearing them I could tell that they stretched some and weren’t so tight across my toes. They were comfortable too. I am generally not hard on shoes so hoping they will hold up well.
