Mishimoto MMBK-F2D-08BK Factory-Fit Boot Kit is 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 our products, the Mishimoto lifetime warranty protects your purchase.
