Mishimoto Performance Intercooler, Sleek Silver, for 2017-2019 Chevrolet/GMC Silverado/Sierra 2500HD/3500HD (6.6L) MMINT-DMAX-17SL

Fits select 2017-2019 Chevrolet Silverado 2500HD/3500HD and GMC Sierra 2500HD/3500HD models equipped with the 6.6L L5P Duramax engine.

Heat is the primary enemy of performance in the L5P Duramax. The Mishimoto performance intercooler replaces the restrictive factory unit with a massive 68mm-thick bar-and-plate core, providing 70% more core volume for superior heat dissipation. To ensure long-term reliability under high boost, this intercooler features durable cast-aluminum end tanks that won't crack or leak like factory plastic units.

This intercooler is designed to optimize airflow, reducing restriction by over 64% compared to stock. The inlet has been enlarged by 6mm and the outlet by 12mm to further improve flow efficiency. Included with the intercooler is a specialized cold-side adapter pipe featuring a DuraCore boot and constant-tension T-bolt clamps. The adapter pipe also includes two bungs that can be drilled and tapped for NPT sensors or water/methanol injection nozzles.
