Upgrade the charge-air cooling system in your 2017-2019 Chevrolet Silverado, Chevrolet/GMC 6.6L Duramax L5P with the Mishimoto MMINT-DMAX-17SL performance intercooler. Designed to reduce intake air temperatures, this high-efficiency intercooler helps support consistent power, improved engine performance, and reliable operation under demanding conditions. Lower intake temperatures can also help protect your turbocharged diesel engine from heat-related stress.
The Mishimoto intercooler features durable cast-aluminum end tanks engineered to resist cracking under elevated temperatures and boost pressures. Its bar-and-plate core is 70 percent thicker than the factory unit for improved heat exchange and maximum cooling capacity. The larger core is also designed to reduce airflow restriction by more than 64 percent compared with the stock intercooler, helping promote efficient charge-air delivery and consistent boost pressure.
This Duramax intercooler includes an adapter cold-side pipe equipped with a DuraCore boot and constant-tension T-bolt clamps for a secure, dependable connection. Two additional bungs in the adapter pipe can be drilled and tapped for sensors or water/methanol injection applications. The increased inlet and outlet sizes further improve airflow, while the sleek silver powder-coated finish provides durable surface protection. Backed by the Mishimoto Lifetime Warranty, this intercooler is engineered for a precise, reliable fit on compatible 2017-2019 GM 6.6L Duramax L5P applications.
