Description
The Mishimoto MMHOSE-WR6-12BK is a direct-fit black silicone radiator hose kit engineered specifically for the 2012-2018 Jeep Wrangler JK 3.6L V6, replacing the factory rubber hoses that are prone to cracking and degradation over time. Built from five layers of silicone reinforced with heat-resistant embedded fibers, this kit pairs an upper and lower radiator hose with four worm-gear clamps for a complete, ready-to-install cooling upgrade. It’s a Performance-grade, vehicle-specific hose kit designed to take on the trail without the reliability concerns of aging rubber.
As part of Mishimoto’s Cooling lineup, this silicone radiator hose kit is built to handle the demands of off-road driving, rock crawling, and daily trail use where factory rubber hoses often fall short. The five-layer silicone construction improves both heat and pressure tolerance compared to stock rubber, carrying a maximum temperature rating of 330°F so coolant keeps flowing reliably when conditions get tough. This hose kit is available in black, blue, or red, with this listing covering the black option, and like every Mishimoto Jeep Wrangler part, it’s backed by the Mishimoto Lifetime Warranty.
