AEM 21-891C Cold Air Intake System for 2022-2025 Subaru WRX (H4-2.4L)
$472.99
This product will be available for sale in 2 weeks, but you can pre-order now to receive 10% discount!
Fits 2022-2025 Subaru WRX models equipped with the H4-2.4L engine.
Replace your vehicle's restrictive factory airbox with the AEM 21-891C Performance Air Intake System. This system is engineered, tuned, and dyno-tested to improve engine aspiration, resulting in increased horsepower and torque across the powerband. The intake features a mandrel-bent aluminum tube for smooth airflow, finished in a durable gunmetal gray powder coating for a professional under-hood appearance.
Central to this kit is an oversized, tapered cylindrical AEM Dryflow synthetic air filter. This oil-free media provides exceptional filtration and airflow while remaining washable and reusable for up to 100,000 miles before servicing is required. To protect intake temperatures from engine bay heat soak, a custom-shaped heat shield with an integrated lid is included.

- Filter Type: Oil-free Dryflow synthetic media (Washable/Reusable)
