An intercooler cools the air after the turbo squeezes it. Cooler air is denser, which is what the engine actually wants. This one is the Mishimoto Mishimoto MMICP-DMAX-11KBK Complete Intercooler Pipe Kit | 2011-2016 GM Silverado/Sierra 2500HD/3500HD 6.6L Duramax LML, listed to fit the 2011-2016 GMC Sierra 2500HD/3500HD with the 6.6L Duramax V8 (LML).
why this one — The gain shows up on repeat hard pulls and towing, where the stock cooler heat-soaks, more than on a single run. Alligator Performance lists it at $729.95, and the fitment above is what the listing itself states, not a guess.
No published gain figure for this part, and nothing here is a guarantee. Price is a list price and can lag the retailer; confirm at checkout. See how we check a price and our affiliate disclosure.
