Upgrade your rotten rubber coolant hoses to these gloss silicone hoses, available in black, blue, and red! The Mishimoto coolant hose kit is the perfect upgrade for the factory rubber hoses on your 12 valve. Mishimoto silicone hoses are crafted from a combination of high-grade silicone and four layers of heat-resistant fibers to provide improved heat reduction, superior durability, and increased pressure tolerance. Old degrading coolant hoses can cause potential engine damage when they fail; avoid this by upgrading to the Mishimoto silicone coolant hose kit. The Mishimoto coolant hose kit retains factory fitment and is available in black, blue, and red. As with all Mishimoto products, this hose kit includes the Mishimoto lifetime warranty.
