Mishimoto Performance Intercooler for 2011-2016 Chevrolet/GMC Silverado/Sierra Duramax (6.6L) - Black (MMINT-DMAX-11BK)

Fits select 2011-2016 Chevrolet Silverado and GMC Sierra 2500 HD/3500 HD models equipped with the 6.6L Duramax engine.

The Mishimoto MMINT-DMAX-11BK Performance Intercooler is engineered to manage the high boost pressures and increased thermal loads common in the LML Duramax. This upgrade replaces the restrictive factory unit with a heavy-duty bar-and-plate core designed for maximum heat soak resistance, making it an essential component for trucks used for heavy towing, hauling, or high-performance street builds.

By utilizing a core that is 73% thicker than the factory original, this intercooler achieves a 101% increase in total core volume. To ensure long-term reliability under high-stress conditions, it features all-aluminum cast end tanks that are precision TIG-welded to the core, eliminating the common failure points associated with plastic-tanked OE units. The black finish provides a clean, stealthy look while offering protection against the elements.
