The Performance Cold Air Intake System AEM 21-772C produces torque and horsepower gains by replacing your vehicle's restrictive factory air filter and air intake housing.
Designed, tuned, and dyno-tested, this air intake system fits specific Subaru Impreza models.
Air enters the system through an oversized AEM Dryflow synthetic washable air filter for outstanding filtration, air flow, and performance.
Located in the original air box space, the air filter is protected by a heat shield designed to reduce intake air temperature and increase horsepower.
Constructed from mandrel-bent aluminum, the air intake tube features a durable gunmetal gray powder coated finish.
Developed to accommodate the engine's factory emissions control devices, including the mass airflow sensor, the tapered cylinder shaped AEM Dryflow air filter is made from an oil-free, synthetic filter media that can be used for up to 100,000 miles before cleaning is needed, depending on driving conditions.
The air intake system is easy to install with commonly available tools and is backed by AEM's Lifetime Limited Warranty.
Some AEM air intakes are not legal for sale or use in California and other states adopting California emission standards, while others are 50 state legal.
