Mishimoto is proud to release a direct-fit silicone boot kit for your Nissan Titan XD. With Duracore™ technology, this boot kit is the perfect upgrade in performance and reliability for your 5.0L Cummins. Mishimoto DuraCore™ technology is the synthetic material that comprises the innermost layer of all Mishimoto silicone diesel boots. Compared to normal silicone, DuraCore™ in our Titan XD performance boots provides superior resistance to heat, pressure, fuel, and oil. This effectively increases the life of our Titan XD performance boots by preventing leaks and blowouts. The Mishimoto Titan XD performance boot kit retains factory fitment for ease of installation, and fits with both stock and Mishimoto Intercooler Piping. To add even more reliability, this kit includes Mishimoto constant-tension T-bolt clamps for accurate and consistent holding power. As with all Mishimoto Titan XD performance parts, this boot kit is protected by our signature Mishimoto Lifetime Warranty.
