Don't let bad factory Powerstroke radiator hoses happen to a good engine. Mishimoto is expanding their line of Powerstroke performance parts to include a 7.3L Powerstroke silicone hose kit. These Powerestroke coolant hoses are manufactured from a combination of high-grade silicone and four layers of heat-resistant embedded fibers to provide the ultimate in durability and performance. Factory rubber Powerstroke coolant hoses will begin to degrade and crack with years of abuse and can cause serious overheating upon failure. Upgrading to Mishimoto Powerstroke radiator hoses ensures peace of mind and improved reliability. The Mishimoto 7.3L Powerstroke silicone hose kit, like all our Powerstroke performance parts, includes our signature Lifetime Warranty. Whether your Ford is stock or modified, trust Mishimoto and our line of Powerstroke performance parts to keep your Powerstroke cool.
