Description
The Mishimoto MMHOSE-GRC-23BK is a black silicone radiator hose kit engineered specifically for the 2023+ Toyota GR Corolla, replacing the factory rubber cooling hoses with a five-layer silicone construction reinforced with heat-resistant embedded fibers. Built to Mishimoto’s Performance grade standard, this kit swaps out the upper and lower radiator hoses along with the expansion tank and ancillary hoses in one complete package designed for a straightforward installation.
Where factory rubber hoses can harden, crack, or fail under sustained heat and pressure, this Mishimoto silicone hose kit is built to resist that kind of degradation, carrying a maximum temperature rating of 330°F. The added heat and pressure tolerance helps protect the GR Corolla’s cooling system while also refreshing the look of the engine bay — this particular kit arrives in black, with blue and red also offered for owners who want to further personalize their GR Corolla. Every hose in the kit ships alongside the stainless-steel worm gear clamps needed for installation, and like Mishimoto’s other GR Corolla cooling components, it’s backed by the Mishimoto Lifetime Warranty.
