The AEM 21‑477P Performance Cold Air Intake replaces the factory intake and relocates an oversized AEM Dryflow washable synthetic air filter to the passenger‑side wheel well to reduce intake temperatures and increase power for select Subaru Impreza WRX/WRX STI, Forester Turbo and Saab 9‑2X models. Mandrel‑bent aluminum tubing and oil‑free filter media offer durable airflow gains, and many AEM intakes carry AEM’s Lifetime Limited Warranty.
