The Mishimoto silicone induction hose for 2001–2007 Subaru WRX and WRX STI (blue) swaps the stock rubber hose for high‑grade silicone with heat‑resistant embedded fibers. Wire reinforcement resists collapsing under pressure and the larger internal diameter promotes increased flow while preserving OEM fitment. Rated to 330°F, it’s a durable, direct‑fit intake upgrade in blue.
