Description
The Mishimoto MMHOSE-SUB-INT6RD is a red silicone intercooler hose kit engineered specifically for Subaru turbocharged applications, replacing the factory rubber intercooler piping with a molded, round silicone design built to handle higher boost pressure and heat than the OEM parts it replaces.
This Fabrication-category kit is built from high-grade silicone reinforced with heat-resistant embedded fibers, giving it a 330°F maximum temperature rating and a Performance grade construction that stands up to the demands of a boosted Subaru intake system. Each hose features a smooth interior surface designed to deliver increased airflow to the intercooler, while the molded round shape retains OEM fitment for a straightforward installation. Beyond raw durability, the increased pressure tolerance of this Mishimoto silicone hose set makes it a practical upgrade for owners looking to move past aging rubber couplers without sacrificing fit or reliability.
