Product Description

The Mishimoto MMHOSE-SUB-IHBK is a performance-grade silicone induction hose designed to replace the OEM corrugated hose on Subaru WRX (2001-2007) and WRX STI (2004-2015) models, as well as select Forester XT, Impreza WRX, and Saab 9-2X Aero variants. Featuring a smooth bore and wire-reinforced design, this hose enhances airflow, minimizes turbulence, and resists collapse under high boost pressure - ideal for daily driving or tuned setups. :contentReference[oaicite:1]{index=1}

Constructed from high-temperature silicone embedded with heat-resistant fibers and wire reinforcement, it withstands operational temperatures up to 330 °F.
