Factory OE rubber heater hoses are prone to degradation over time, causing leaks and blowouts. Aeroflow have created a range of OEM factory fit silicone heater hose complete engine kits. Each of the heater hose in the kit is constructed from 4-ply silicone with heat-resistant fibres for superior heat and pressure tolerances. Silicone hoses are far more durable, reliable, and less prone to degradation than the factory rubber hoses making this a great upgrade for your cooling system. They are designed for specific makes and models and feature a smooth gloss black finish.
