AEM Cold Air Intake System for 2015-2021 VA Subaru STi (21-863C)
AEM® cold air intake systems are engineered to boost horsepower and torque, featuring an oversized AEM DRYFLOW® synthetic washable air filter for superior airflow, filtration, and performance. Custom-engineered tubes deliver better airflow than you get with a stock intake. More air means better performance.
The system includes a mandrel-bent aluminum intake tube, high-quality hardware, and a custom heat shield to protect intake air from engine bay heat. The conical filter design allows up to 100,000 miles between services under normal highway driving. Installation typically takes less than 90 minutes. Note that some intakes may not be legal for use in California; check product specifications for CARB status for your vehicle.
