Mishimoto 17-19 GM 6.6L L5P Duramax Intercooler - Silver - MMINT-DMAX-17SL

Mishimoto has expanded its line of Duramax performance parts to include a performance intercooler for the 2017-2019 Chevrolet/GMC 6.6L Duramax L5P. High intake temperatures can reduce performance and potentially cause engine damage if left unchecked. Protect your engine by upgrading to the Mishimoto 6.6L Duramax L5P performance intercooler.

This Duramax intercooler is precision engineered with durable cast-aluminum end tanks that resist cracking under high temperatures and boost pressures. The massive 68mm-thick bar-and-plate core is 70% thicker than stock and is designed for maximum cooling. In addition, the larger core reduces restriction by over 64% compared to the stock intercooler.

Mishimoto has also increased the size of the intercooler inlet and outlet by 6mm and 12mm, respectively, to improve flow even more. Included with this intercooler is an adapter cold-side pipe with DuraCore™ boot and constant-tension T-bolt clamps. Two additional bungs on the adapter pipe can be drilled and tapped for sensors or water/meth injection. Offered in Sleek Silver or Stealth Black powder-coated finish, the Mishimoto 6.6L Duramax intercooler, like every Mishimoto Duramax part, is protected by the Lifetime Warranty.
