Installation Note: Silicone hose water permeation rate is 10 to 15 times greater than standard EPDM rubber hose. Checking coolant level regularly is highly recommended when silicone coolant hoses are used in a daily driving vehicle.

Backed by HPS Performance Products' limited lifetime warranty, this silicone heater hose kit is a reliable, long-lasting upgrade over the factory rubber hoses.
