Description
The Mishimoto MMBK-F2D-08CU is a direct-fit silicone cold side, upper boot built with Mishimoto’s DuraCore technology, engineered specifically for the 2008-2010 Ford 6.4L Powerstroke. This boot kit replaces the weak factory pipe (part number 8C3Z-6N650-A) with a purpose-built silicone piece designed to hold up where the stock component struggles.
As part of a healthy air intake system, the cold side boot routes charge air through the intake tract, and a boot that cracks or collapses under heat and pressure can undermine the performance of the entire air intake setup. Mishimoto’s DuraCore technology forms the innermost layer of this silicone boot, offering superior resistance to heat, pressure, fuel, and oil compared to standard silicone, which helps prevent leaks and blowouts and extends the service life of the boot. The kit is rounded out with Mishimoto constant-tension T-bolt clamps for accurate, consistent holding power, so the connection stays secure through repeated heat cycles. This boot kit is precision engineered for a flawless fit and is backed by the Mishimoto Lifetime Warranty.
