AEM Induction IND Cold Air Intakes

AEM Induction IND Cold Air Intakes Upgrade airflow, throttle response and engine character with the AEM Induction IND Cold Air Intake (21-836WR). Engineered and dyno-tested specifically for select Subaru WRX STI models, this system replaces the restrictive factory intake to deliver measurable horsepower and torque gains while maintaining compatibility with factory emissions controls. High-flow AEM Dryflow® filter — Oversized, tapered cylinder design with oil-free synthetic media for exceptional airflow and filtration. Washable and reusable; service interval up to 100,000 miles depending on conditions. Heat-shielded installation — Filter sits in the original airbox location and is protected by a purpose-built heat shield to reduce intake air temperatures and maximize performance. Durable intake tubing — Mandrel-bent aluminum construction with textured red powder coat for strength, fitment precision and long-lasting corrosion resistance. Emissions-friendly — Designed to retain factory emission control devices including the mass air flow sensor for reliable operation and compliance where applicable. Easy bolt-on fitment — Uses common hand tools for a straightforward installation and is backed by AEM’s Lifetime Limited Warranty. Note: Some AEM intakes are not legal for sale or use in California and other states adopting California emissions standards.
