Protect your on and off road adventures in your 2010-2021 Toyota 4Runner with the Mishimoto silicone Radiator Hose Kit. Our kit replaces the degradation prone stock rubber hosing with 5 layers of durable silicone embedded with heat-resistant fibers. The Mishimoto kit includes the upper and lower radiator hoses in rugged silicone to not only prolong the lifespan of the cooling system, but also spruce up the engine bay of your 4Runner. This kit is available in blue, red, and black to match your style, and like all of our products, includes the Mishimoto Lifetime Warranty.
