Mishimoto engineers know you love your Ford which is why we've developed a line of Powerstroke performance parts including a direct-fit silicone boot kit with DuraCore™ technology designed specifically for the 7.3L Ford Powerstroke. 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, petrol, and oil. This effectively increases the life of our boots by preventing leaks and blowouts.To add further reliability, this kit includes Mishimoto Constant Tension T-bolt Clamps for accurate and consistent holding power. These Powerstroke performance boots are engineered to retain perfect factory fitment for use on your stock or modified 7.3L. As with all our Powerstroke performance parts, this boot kit includes the Mishimoto Lifetime Warranty. Whether your Ford is stock or modified, trust Mishimoto and our line of Powerstroke performance parts to keep your Powerstroke cool.
