15+ WRX / 14+ FXT Silicone Radiator Hose Kit by Mishimoto

Rubber is out, silicone is in! Upgrade your stock 2015 WRX radiator hoses with the Mishimoto Silicone Radiator Hose Kit to provide your 2015 WRX with an advancement in both style and reliability. This 2015 WRX kit includes the upper radiator hose, lower radiator hose, overflow port hose, as well as four worm-gear clamps to make these 2015 WRX parts easy to install. Unlike the degradation-prone stock rubber hoses, the Mishimoto 2015 WRX hoses are constructed from four layers of silicone with heat-resistant embedded fibers to provide unmatched durability, heat tolerance, and pressure tolerance. Whether you are entering your 2015 WRX in the local rallycross, or lapping at your next track day, trust Mishimoto and our line of 2015 WRX parts to keep your WRX cool. This 2015 WRX hose kit is available in black, blue, or red and, like our entire line of 2015 WRX parts, includes the signature Mishimoto Lifetime Warranty.
