Mishimoto Silicone Radiator Hose Kit for 2008-2014 Subaru WRX & STI (Blue)

Elevate the cooling performance and aesthetics of your 2008-2014 Subaru WRX or 2008+ STI with the striking blue Mishimoto Silicone Radiator Hose Kit. Factory rubber hoses are a common failure point, susceptible to cracking and leaks. Mishimoto's premium silicone hoses provide a durable, high-performance alternative engineered to withstand extreme engine conditions.

Engineered for Superior Cooling and Longevity

This kit is designed as a direct replacement for your stock radiator hoses, offering significant advantages:

  • Advanced Silicone Construction: Composed of five layers of high-grade silicone, reinforced with heat-resistant fibers for exceptional strength and resistance to heat soak and pressure.
  • Optimized Coolant Flow: The smooth internal surface and precise diameter ensure efficient coolant circulation, helping to maintain optimal engine temperatures.
  • Resists Degradation: Unlike rubber, silicone is resistant to coolant chemicals, ozone, and UV exposure, ensuring a longer service life.
  • Wire-Reinforced Design: Prevents the hose from collapsing under vacuum, guaranteeing consistent performance during spirited driving or track use.

Vibrant Blue Finish

The eye-catching blue color adds a custom touch to your engine bay, showcasing your commitment to performance and quality. This kit includes all necessary high-quality worm gear clamps for a secure and straightforward installation. Equip your Subaru WRX or STI with the ultimate cooling solution from Mishimoto and drive with confidence.
