AEM Induction 21-891C Performance Cold Air Intake for 2022-2024 Subaru WRX 2.4L H4 Turbo

This Performance Air Intake System allows your engine to breathe more air compared to the restrictive factory air intake housing. It is designed, tuned and dyno-tested to produce more horsepower and torque. Air enters the system through an oversized AEM Dryflow synthetic washable air filter for outstanding air flow, filtration and performance. The air intake tube is constructed from mandrel-bent aluminum featuring a durable gunmetal gray powder coated finish. A custom shaped heat shield with lid is included. 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). AEM's Performance Cold Air Intake Systems are designed, tuned and dyno-tested to give your engine more power and acceleration by replacing the restrictive factory air filter, air intake tubing and air box assembly.
