Treat your stock or modified Cummins to an upgrade in reliability with the Mishimoto silicone Coolant Hose Kit engineered specifically for the 2010-2012 6.7L. This kit replaces the factory upper and lower radiator hoses with 100-percent silicone components. Mishimoto hoses are constructed from high-grade 4-ply silicone with heat-resistant embedded fibers for superior heat and pressure tolerance. Silicone hoses are far more durable, reliable, and less prone to degradation than the factory rubber counterparts. Similar to the stock lower hose, the Mishimoto silicone lower hose utilizes an internal spring to prevent hose collapse. This kit is available in red, black, or blue and includes the Mishimoto Lifetime Warranty, ensuring superior product quality and craftsmanship.
