Mishimoto is proud to expand their Cummins performance line to include a direct-fit silicone boot kit with DuraCore™ technology designed specifically for the 2019+ 6.7L Dodge Cummins. High-powered Cummins vehicles require Cummins performance products, which is why our boot kits are manufactured using DuraCore™ technology. Mishimoto DuraCore™ technology is the synthetic material that comprises the innermost layer of all Mishimoto silicone diesel boots. Compared to normal silicone, DuraCore™ provides superior resistance to heat, pressure, fuel, and oil. This effectively increases the life of our boots by preventing leaks and blowouts. To add even more reliability, this Cummins performance kit includes Mishimoto Constant Tension T-bolt Clamps for accurate and consistent holding power. The Mishimoto Cummins performance boot kit maintains factory fitment and like all of our Cummins performance parts, is protected by the signature Mishimoto Lifetime Warranty
