Description
The Mishimoto MMINT-DMAX-17SL is a purpose-built performance intercooler engineered specifically for the 2017-2019 Chevrolet/GMC 6.6L Duramax L5P. At the heart of this Duramax performance part is a massive 68mm-thick bar-and-plate core, 70-percent thicker than the factory unit, paired with cast-aluminum end tanks designed to resist cracking under the heat and boost pressure a Duramax generates.
High intake temperatures can rob performance and put unnecessary stress on your engine over time. As a key component of your truck’s forced induction system, this Mishimoto intercooler is built to move more air with less restriction, cutting flow restriction by over 64-percent compared to the stock intercooler while a larger inlet and outlet further improve flow through the induction system. Whether you’re upgrading a factory-stressed forced induction setup or simply want a more durable induction engine component that can take repeated heat cycles, this performance induction upgrade is engineered to keep intake temps in check and protect your investment.
