Fits select 2017-2019 Chevrolet Silverado 2500 HD/3500 HD and GMC Sierra 2500 HD/3500 HD (6.6L L5P Duramax).

Manage high intake temperatures and protect your L5P engine with the Mishimoto Stealth Black Performance Intercooler. Engineered for heavy-duty use, this intercooler replaces the restrictive factory unit with a massive 68mm-thick bar-and-plate core. By increasing core thickness by 70%, Mishimoto has achieved a 64% reduction in flow restriction compared to stock, ensuring your 6.6L Duramax breathes easier under load.

The unit features precision-engineered cast-aluminum end tanks designed to withstand high boost pressures and thermal cycling that often cause plastic OE tanks to fail. The inlet and outlet sizes are expanded by 6mm and 12mm respectively to further optimize airflow. This kit includes an adapter cold-side pipe equipped with a DuraCore boot and constant-tension T-bolt clamps for a secure, leak-free installation.
