Description

AEM Cold Air Intake System for Subaru WRX (2015ƒ??2020)

The AEM 21-732C Cold Air Intake System is built to unlock the performance potential of your 2015ƒ??2020 Subaru WRX 2.0L H4 F/I engine. Designed, tuned, and dyno-tested specifically for WRX models, this system replaces the restrictive factory air intake and filter, allowing greater airflow and improved power output. Air is drawn through an oversized AEM Dryflow synthetic air filter, housed in the factory air box location and shielded from heat to ensure cooler intake temperatures. The intake tube is constructed from mandrel-bent aluminum and coated in a sleek, gunmetal gray finish for durability and a premium look. This intake system supports all factory emissions devices and includes accommodations for the mass air flow sensor. Installation is simple, and with oil-free filtration and a long service interval, it offers both power and practicality. Note that emissions legality may vary by state.
