Specifications Part Details: The COBB Silicone Radiator Hose Kit is designed to replace the factory rubber radiator hoses on the Subaru WRX with a more durable and heat-resistant silicone solution. This upgrade helps improve cooling system reliability by reducing the risk of hose degradation under elevated temperatures and pressure. Engineered as a direct-fit replacement, this hose kit installs using factory routing and connection points. Silicone construction offers improved resistance to heat, pressure, and long-term wear compared to OEM rubber hoses, making it a practical upgrade for both daily-driven and modified WRX setups. Design & Durability COBB silicone radiator hoses are constructed using multi-layer silicone reinforced with heat-resistant fibers. This design improves structural integrity and helps maintain consistent coolant flow under demanding operating conditions. Compared to factory rubber hoses, silicone hoses provide improved longevity and are less prone to cracking, swelling, or failure over time.
