OVERVIEW

Prevent coolant leaks and maintain an OEM-plus look in your engine bay with the Mishimoto Black Silicone Radiator Hose Kit for the 2023+ Toyota GR Corolla. Standard factory rubber hoses degrade over time when subjected to constant heat cycles and pressure, leading to cracks and potential failure on the street or track. Constructed from five layers of premium black silicone embedded with heat-resistant fibers, this kit offers heightened temperature tolerance, superior pressure resistance, and lasting durability with a stealthy factory appearance. Designed as a direct fit for a hassle-free installation, it includes high-quality stainless steel worm gear clamps to completely refresh your GR Corolla's cooling plumbing.
