11537830716, upper radiator hose
11537830715, lower radiator hose

These high quality silicone hoses feature stock-type quick-disconnect fittings - no need to cut up your old hoses to get the connectors off! Unlike factory rubber hoses, silicone can withstand higher temperatures and pressures with minmal wear. Rubber will wear out and weaken so don't let it bite you when it counts! Silicone has been proven during extreme racing conditions and won't be the weak link that ruins your day.
The pre-attached stock-style plastic quick-disconnect fittings include new O-rings, providing a reliable leak-free seal during installation. We do not recommend re-using the temp sensor located in the lower radiator hose. You can add a new one to your order from the options below.
