AEM engineers design our short ram and cold air intake systems as a fully integrated component of the vehicle. Significant testing is performed to assure proper airflow management with the goal of keeping inlet air temperature (IAT) at or near ambient air temperature. AEM intake designers seek to create air intake systems that produce the highest power gains in the RPM range that will most enhance the driving experience. AEM intakes take advantage of several tuning methods to create power gains that are repeatable, safe, and consistent.
AEM has a solid reputation within Subaru enthusiast communities for creating Subaru short ram and cold air intake systems which boost horsepower and torque for WRX, WRX STi, BRZ, Forester, Impreza RS, Legacy, and Outback models. Additionally, AEM has streamlined its internal processes to make obtaining an Exemption Order (EO) from the California Air Resource Board (CARB) efficient. Obtaining an EO from CARB makes our air intake systems available for sale and use in California as well as all other states with similar emissions standards. Southern California has one of the densest populations of Subaru fans, and these owners are able to boost performance of their WRX, WRX STi, BRZ, Forester, Impreza RS, Legacy, or Outback without worrying about being hassled at their car’s next smog check.
