Why upgrade

It's been a decade since the 2013-2018 RAM 6.7L Cummins began to roll off the assembly line. While robust and reliable, the 2013-2018 RAM 6.7L Cummins is only partially immune to the test of time. Stock components, like the plastic degas tank, become brittle and cloudy over time, making it prone to leaks and impossible to see the coolant level. Mishimoto engineers these kits around real chassis packaging, so hoses, coolers and adapters line up without fabrication on the listed years. Follow the published torque specs and install guide, reuse sensors where instructed, and confirm clearances if you run other supporting mods. Every unit ships with the Mishimoto Lifetime Warranty for as long as you own it.
