Description
The Mishimoto MMBK-F2D-08HL is a direct-fit, hot side lower silicone boot engineered with Mishimoto’s proprietary DuraCore technology specifically for the 2008-2010 Ford 6.4L Powerstroke. This boot kit replaces the factory pipe (part number 8C3Z-6W651-A) that can wear out under the stress of turbocharged diesel operation, pairing a DuraCore-reinforced silicone boot with Mishimoto constant-tension T-bolt clamps for a durable, leak-resistant connection point in your truck’s air intake system.
Where lesser air intake components can crack, swell, or blow apart under sustained heat and boost pressure, this Mishimoto boot is built to resist heat, pressure, fuel, and oil, helping protect the integrity of the connection between your Powerstroke’s intake plumbing. The included constant-tension T-bolt clamps maintain consistent clamping force through repeated heat cycles, reducing the chance of leaks that can undermine any air intake system. It carries a maximum temperature rating of 428°F, and Mishimoto recommends an installation torque of 27 in-lbs (3NM) for the T-bolt and constant-tension T-bolt clamps, which have an operating range of 18-35 in-lbs (2-4NM); the maximum torque rating of 35 in-lbs (4NM) should never be exceeded. Backed by the Mishimoto Lifetime Warranty, this precision-engineered boot kit is designed to deliver years of reliable service as part of your truck’s air intake system.
