Mishimoto is proud to release a direct-fit silicone boot with DuraCore technology designed specifically for the 6.0L Ford Powerstroke. Mishimoto DuraCore technology is 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 our boots by preventing leaks and blowouts. To add even more reliability this kit includes Mishimoto constant tension T-bolt clamps for accurate and consistent holding power. This boot kit is precision engineered for a flawless fit on your Powerstroke and will provide years of service. Like all Mishimoto Powerstroke performance parts, this Powerstroke performance boot kit comes with the Mishimoto Lifetime Warranty. 2008-2010 Ford F-250 Super Duty 6.4 Liter, 2008-2010 Ford F-350 Super Duty 6.4 Liter, 2008-2010 Ford F-450 Super Duty 6.4 Liter DuraCore technology provides superior resistance to heat, pressure, fuel, and oil Replaces weak factory pipe (part number 8C3Z-6W650-A) Includes high-quality constant-tension T-bolt clamps Fitment: Ford F-250 Super Duty Cabela’s 2009 to 2010 Ford F-250 Super Duty FX4 2008 to 2009 Ford F-250 Super Duty Harley-Davidson Edition 2008 to 2010 Ford F-250 Super Duty King Ranch 2008 to 2010 Ford F-250 Super Duty Lariat 2008 to 2010 Ford F-250 Super Duty XL 2008 to 2010 Ford F-250 Super Duty XLT 2008 to 2010 Ford F-350 Super Duty Cabela’s 2009 to 2010 Ford F-350 Super Duty FX4 2008 to 2009 Ford F-350 Super Duty Harley-Davidson Edition 2008 to 2010 Ford F-350 Super Duty King Ranch 2008 to 2010 Ford F-350 Super Duty Lariat 2008 to 2010 Ford F-350 Super Duty XL 2008 to 2010 Ford F-350 Super Duty XLT 2008 to 2010
