Description
The Mishimoto MMHOSE-GRC-23BL is a direct-fit silicone radiator hose kit engineered specifically for the 2023+ Toyota GR Corolla, replacing the factory rubber hoses with a five-layer silicone construction reinforced with heat-resistant embedded fibers. Finished in a bold blue, this Mishimoto Cooling upgrade swaps out every major coolant hose in the GR Corolla’s engine bay for a cleaner look and stronger resistance to heat and pressure.
Built to a Performance grade and rated to withstand up to 330°F, this silicone hose kit is designed to outlast OEM rubber hoses that can crack, soften, or leak over time. Because it’s a vehicle-specific fit rather than a universal hose, every hose in the kit is shaped to match the factory routing of the GR Corolla, so there’s no cutting, trimming, or guesswork during installation. The kit ships complete with stainless-steel worm gear clamps, making it a straightforward upgrade for anyone looking to refresh their GR Corolla’s cooling system while adding a splash of color under the hood.
