Description
The Mishimoto MMHOSE-F250D-99BL is a blue silicone coolant hose kit purpose-built for the 7.3L Powerstroke, replacing the factory rubber hoses that are prone to cracking and rapid deterioration from years of heat, pressure, and abuse. Engineered to retain factory fitment, this specific-fit kit is manufactured from a combination of high-grade silicone and four layers of heat-resistant embedded fibers for improved durability where the stock hoses fall short.
Cooling system reliability starts with hoses that can handle sustained heat and pressure, and that is exactly what this Mishimoto silicone coolant hose kit is designed to deliver. The performance-grade silicone construction increases pressure tolerance, efficiently reduces heat, and helps guard against blowouts, giving the 7.3L Powerstroke cooling system a more robust upgrade path than the aging factory rubber hoses it replaces. Every Mishimoto cooling product, including this hose kit, is backed by the Mishimoto lifetime warranty.
