Description
The Mishimoto MMHOSE-SUB-INTBK is a black silicone intercooler hose kit engineered specifically for the turbocharged Subaru WRX platform. Built from four hand-wrapped layers of high-grade silicone reinforced with heat-resistant embedded fibers, this Mishimoto Fabrication piece is designed to handle elevated boost pressure and heat while delivering a smooth interior surface for maximum airflow to the WRX top-mount intercooler.
As part of Mishimoto’s Fabrication lineup, this hose kit replaces aging factory rubber piping with a durable silicone alternative engineered for a direct OEM replacement fit. The kit’s smooth interior bore is intended to efficiently reduce heat and increase pressure tolerance compared to stock hoses, making it a practical upgrade for anyone maintaining or building out their WRX’s intake and intercooler piping. Mishimoto backs the kit with clamps needed for installation and offers the hoses in black, blue, or red so you can match the style of your engine bay — this listing is the black version.
