Mishimoto is proud to release a direct-fit silicone boot kit with DuraCore™ technology designed specifically for the 6.4L 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, fuel, and oil. This effectively increases the life of our 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. As with all of our Powerstroke performance parts, this boot kit comes with the Mishimoto Lifetime Warranty.
Mishimoto Automotive (“Mishimoto”) warrants its products under this lifetime limited warranty policy (“Warranty Policy”). This Warranty Policy applies solely to: (i) Mishimoto Products purchased directly from Mishimoto or Mishimoto authorized dealers (each a “Mishimoto Product” and collectively, the “Mishimoto Products”) and (ii) the original purchaser of such Mishimoto Product (“Purchaser”). This Warranty Policy is non-transferable and all claims under this Warranty Policy must be accompanied by the original sales receipt. The terms and conditions of this Warranty Policy are subject to change by Mishimoto at any time without notice.
