A blown intercooler boot can mean the end to a weekend at the drag strip or a canceled day on the boat. You demand a lot from your truck, so you need reliable and dependable parts. Mishimoto is proud to release a direct-fit silicone boot kit with DuraCore technology designed specifically for the 6.6L Chevrolet/GMC Duramax. 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 boots by preventing leaks and blowouts. To add even more reliability this kit includes Mishimoto constant-tension T-bolt clamps for accurate and consistent holding power..
