Description
The Mishimoto MMHOSE-GRC-23RD is a direct-fit silicone radiator hose kit built specifically for the 2023+ Toyota GR Corolla, finished in a bold red for owners who want their engine bay to look as sharp as their car performs. Unlike the factory rubber hoses, which can dry out, crack, and fail over time, this kit is constructed from five layers of silicone with heat-resistant embedded fibers, giving it a Maximum Temperature Rating of 330°F and Performance-grade construction rated for Specific fitment rather than a universal application.
This Mishimoto Cooling system upgrade is designed to eliminate the leak and tear risk associated with aging rubber hoses while improving heat and pressure tolerance under the hood of your GR Corolla. The kit includes both the upper and lower radiator hoses along with the expansion tank hoses and an ancillary hose, so your entire coolant hose circuit gets refreshed in one shot rather than piecemeal. Ten stainless-steel worm gear clamps are included for a hassle-free, hardware-complete installation, and the red silicone hoses let you personalize the look of your engine bay in addition to boosting durability and reliability over the stock setup.
