Mishimoto Black Intercooler Kit - Chevrolet/GMC 6.6L Duramax LML 2011-2016

The Mishimoto intercooler kit replaces the factory unit on the 2011-2016 6.6L LML Duramax with a bar-and-plate core that carries 101% more core volume and runs 73% thicker than stock, dropping intake temperatures and EGTs. Precision TIG-welded cast aluminum end tanks remove the failure points of stamped OE tanks. The kit includes mandrel-bent aluminum charge pipes (3.5in cold side and 3.0in hot side), silicone boots, clamps, and mounting hardware for a complete bolt-on install.
