- Engine size. For engine parts, make sure the engine size on the product matches your engine.

- Body style. Sedan or hatch, two-door or four-door, cab and bed length on trucks.

Mishimoto is proud to release a direct-fit silicone boot kit with DuraCore(TM) technology designed specifically for the 2017-2019 Chevrolet/GMC 6.6L L5P Duramax. Mishimoto DuraCore(TM) technology is a synthetic material that comprises the innermost layer of all Mishimoto silicone diesel boots. Compared to normal silicone, DuraCore(TM) 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, these couplers feature stainless-steel reinforcing rings to prevent expansion under high pressure that may result in a blowout and lost boost pressure. This kit also includes Mishimoto stainless-steel constant-tension T-bolt clamps for a reliable and consistent seal. As with all our products, this boot kit is protected by the Mishimoto Lifetime Warranty.
- Five layers of 100-percent silicone for maximum durability and blowout prevention
- Stainless-steel reinforcing rings help prevent expansion under high pressure
- Includes mounting point for air temperature sensor harness
