Cobb 15-21 Subaru WRX / 14-18 Forester XT Silicone Radiator Hose Kit

COBB is known for making well-built performance parts for Subaru vehicles. This silicone radiator hose kit is designed to replace the stock rubber hoses on your 2015-2021 Subaru WRX or 2014-2018 Forester XT. Stock rubber hoses can degrade over time, especially under the stress of performance driving or higher engine temperatures, leading to leaks or bursts. These silicone hoses offer a more robust solution.

Constructed from multi-layer silicone with polyester reinforcement, these hoses are built to handle higher temperatures and pressures than standard rubber. The smooth interior surface also helps maintain consistent coolant flow. This kit includes both the upper and lower radiator hoses, providing a complete replacement for the aging factory components.
