Specifications
Part Details:
The Mishimoto Silicone Radiator Hose Kit is designed to replace the factory rubber radiator hoses on the Subaru WRX and STI with a more durable and heat-resistant silicone solution. This upgrade helps improve long-term reliability by reducing the risk of hose degradation under heat and pressure.
Engineered as a direct-fit replacement, this hose kit installs using factory routing and connection points. Silicone construction provides improved resistance to heat, pressure, and wear compared to OEM rubber hoses, making it a practical upgrade for both daily-driven and performance-focused vehicles.
Design & Durability
Mishimoto silicone radiator hoses are constructed from multiple layers of silicone reinforced with heat-resistant embedded fibers. This multi-layer design improves structural integrity and helps maintain consistent coolant flow even under elevated operating temperatures.
Compared to aging factory hoses, silicone hoses offer improved longevity and reduced likelihood of cracking, swelling, or failure over time.
