Description
The Mishimoto MMBK-F2D-03CU is a direct-fit black silicone cold side, upper boot built with Mishimoto’s DuraCore technology, engineered specifically to replace the weak factory pipe (part number 6C3Z-6C640-BA) on the 2003-2004 Ford 6.0L Powerstroke. As part of Mishimoto’s Air Intake Systems lineup, this boot is manufactured from five layers of silicone with heat-resistant embedded fibers and is precision engineered for a flawless fit that will provide years of service.
DuraCore is the synthetic material that forms the innermost layer of every Mishimoto silicone diesel boot in this air intake system, and compared to standard silicone it delivers superior resistance to heat, pressure, fuel, and oil. That added resistance extends the life of the boot by helping prevent leaks and blowouts along the intake path. To back up that durability, this performance-grade, specific-fit kit includes Mishimoto constant tension T-bolt clamps that provide accurate, consistent holding power at the connection points, and the entire kit is backed by the Mishimoto Lifetime Warranty.
Vehicle Applications
This boot kit is a specific fit for 2003-2004 Ford Excursion Eddie Bauer, Limited, and XLT models, along with the Excursion XLS for 2004. It also fits the 2003-2004 Ford F-250 Super Duty Lariat, XL, and XLT, as well as the F-250 Harley-Davidson Edition and King Ranch trims for 2004. Coverage extends to the 2003-2004 Ford F-350 Super Duty King Ranch, Lariat, XL, and XLT, with the F-350 Harley-Davidson Edition covered for 2004. Rounding out fitment, the 2003-2004 Ford F-450 and F-550 Super Duty Base, Lariat, XL, and XLT trims are also covered — all equipped with the 6.0L Powerstroke. Owners running the 2003-2004 truck can also source this cold side, upper boot broken out individually from the MMBK-F2D-03CBK kit, while 2005-2007 Powerstroke owners can upgrade their factory plastic pipe to the Mishimoto MMICP-F2D-03C.
