The AEM cold air intake for 2008–2014 Subaru WRX/STi replaces the factory intake with a mandrel-bent aluminum tube, oversized DRYFLOW washable synthetic filter, and a custom heat shield to isolate intake air from engine heat. Engineered to increase horsepower and torque while preserving MAF calibration, the system offers long filter service intervals and a usually straightforward install that enhances airflow and under-hood appearance.
