The Mishimoto MMBK-F2D-08CL Factory Fit Cold-Side Lower Boot is a direct replacement for your 2008-2010 Ford 6.4L Powerstroke. The Mishimoto direct-fit silicone boot features Mishimoto DuraCore technology as 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 Mishimoto boots by preventing leaks and blowouts.

To add even more reliability, this boot includes Mishimoto constant tension T-bolt clamps for accurate and consistent holding power. This boot kit is precision engineered for a flawless fit on your Powerstroke and will provide years of service. Like all Mishimoto Powerstroke performance parts, this Powerstroke performance boot comes with the Mishimoto Lifetime Warranty.
