Enhance your Subaru WRX's performance with the AEM 21-732C Cold Air Intake System from AEM Induction. Designed, tuned, and dyno-tested specifically for 2015 to 2018 Subaru WRX models, this system delivers increased horsepower and torque by replacing the factory air filter and intake housing with a high-flow, oversized Dryflow synthetic washable air filter. The filter's design allows for outstanding airflow and filtration, ensuring your engine breathes cleaner and more efficiently. Located within the original air box space and protected by a heat shield, this setup reduces intake air temperature to maximize power output and acceleration. The heat shield is engineered to guard the intake air from engine bay heat, further improving performance and responsiveness.
Constructed from mandrel-bent aluminum tubing with a durable gunmetal gray powder-coated finish, the intake tubing provides smooth, unrestricted airflow paths. The system is compatible with your vehicle's factory emissions controls, including the mass airflow sensor, ensuring compliance and seamless integration. The tapered cylinder shape of the Dryflow filter is made from oil-free synthetic media that can last up to 100,000 miles before cleaning, depending on driving conditions. Installation is straightforward using common tools, making it accessible for DIY enthusiasts. Backed by AEM's Lifetime Limited Warranty, this cold air intake system offers a reliable upgrade for those seeking more power and better throttle response.
Note that some AEM intake systems may not be legal for sale or use in California and other states with strict emission standards. Verify the legal status for your vehicle model before installation. This product is EPA compliant and meets all necessary standards for performance upgrades without compromising emissions compliance. Improve your Subaru WRX's engine efficiency and driving experience with this high-quality cold air intake system from AEM Induction.
