Description
The Mishimoto MMBK-F2D-08CL is a direct-fit, cold side, lower silicone boot engineered specifically for the 2008-2010 Ford 6.4L Powerstroke. Built with Mishimoto’s DuraCore technology as the innermost layer, this boot is designed to outlast the factory pipe it replaces (Ford part number 8C3Z-6N651-A) while standing up to the extreme conditions found in the intake system of a diesel Super Duty.
As part of your air intake system, this boot connects critical components and must reliably handle heat, pressure, fuel, and oil exposure without leaking or blowing out. Compared to standard silicone used in many cold air intake and cold air induction components, DuraCore technology provides superior resistance to these conditions, which helps extend the service life of the boot. To reinforce that durability, Mishimoto includes constant-tension T-bolt clamps in the kit, delivering accurate and consistent holding power at the connection points. Whether you’re maintaining your factory intake filter setup or upgrading other parts of your intake system, a properly sealed boot like this is essential to keeping air, pressure, and fluids where they belong.
