Description
The Mishimoto MMHOSE-CIV-12SIBK is a purpose-built Silicone Coolant Hose Kit engineered specifically for the K24Z7 engine found in the 2012-2015 Honda Civic Si. Unlike a generic hose, this kit is molded to replace the factory upper and lower radiator hoses on this exact chassis, giving you a direct-fit upgrade rather than a universal cut-to-length piece. It’s offered in black, and this listing covers that black colorway.
Factory rubber radiator hoses can soften, crack, or fail after repeated exposure to heat and pressure, a real risk during spirited street driving or track days. Mishimoto’s answer is a multiple-layer silicone construction reinforced with heat-resistant embedded fibers, built to handle sustained thermal and pressure loads far better than the stock rubber it replaces. Because this is Performance-grade Cooling equipment, it’s designed to greatly outlast the factory hoses while also refreshing the look of your engine bay. The kit is backed by the Mishimoto Lifetime Warranty for added peace of mind.
