Description
The Mishimoto Subaru Impreza STI JDM Silicone Intercooler Hoses (MMHOSE-SUBJ-INT4BK) are a black, four-piece silicone hose kit engineered specifically for the JDM STI intercooler piping layout. Built from high-grade silicone reinforced with heat-resistant embedded fibers, this Mishimoto Fabrication product is designed to handle high under-hood temperatures and the added boost pressure that comes with a performance-oriented STI build.
Each hose in this kit features a smooth interior surface that helps deliver increased airflow to the intercooler, while the embedded fiber construction efficiently reduces heat transfer and boosts pressure tolerance beyond what a stock hose typically offers. Because the hoses are molded to retain OEM fitment, installation follows the factory routing, so you gain a performance upgrade in both durability and looks without reworking the original intercooler piping. Offered here in black (blue and red are also available from Mishimoto), this kit is a straightforward way to replace aging or degraded factory hoses with a more robust silicone alternative built for sustained boost and heat exposure.
