Construction & Design

The Mishimoto hose kit is expertly crafted from a high-quality silicone compound reinforced with four layers of heat-resistant fibers. This multi-layer construction provides outstanding durability against heat, pressure, and environmental wear, far surpassing the lifespan of factory rubber hoses. Unlike OEM hoses that can degrade and become brittle over time, Mishimoto silicone hoses maintain flexibility and strength even after prolonged exposure to high engine temperatures.

Each hose is precision-molded to replicate the exact shape and dimensions of the original equipment, ensuring a perfect fit without trimming or adjustments. The smooth silicone interior surface promotes improved coolant flow and reduces the risk of buildup or blockages within the cooling system, supporting optimal engine temperature regulation.
