Mishimoto is proud to expand our Nissan Titan XD performance line to include a direct - fit Silicone Coolant Hose Kit for your 5.0L Cummins. Our direct - fit coolant hoses are the ideal upgrade from the factory rubber hoses. Factory rubber hoses are a known weak point on any vehicle especially over time, but the Mishimoto silicone hoses are a substantial upgrade in reliability and performance. We want you to get the absolute best from your truck, so we constructed our Titan XD radiator coolant hoses from a combination of high - grade silicone and four layers of heat - resistant embedded fibers to provide superior reliability, durability, and performance. Mishimoto Titan XD coolant hoses exhibit perfect factory fitment and are available in black, blue, and red. As with all our Titan XD performance parts, these Titan XD radiator hoses are protected by the Mishimoto Lifetime Warranty.
