The Mishimoto Factory Fit Hot-Side Upper Boot is a direct replacement for your 2003-2007 Ford 6.0L 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.
