AEM Cold Air Intake Polished 2004-2007 STI / 2006-2007 WRX

AEM Intake Systems are designed to increase horsepower and torque gains as well as better engine sound when used as a replacement for the factory airbox and air filter. AEM intake systems are designed, tuned, and dyno-tested for vehicle specific applications. 

These kits include an oversized AEM Dryflow synthetic washable air filter for optimum air flow, filtration, and performance while allowing easy oil-free cleaning. 

AEM intake systems use mandrel-bent aluminum intake tubes, and high quality hardware designed to reduce restriction and reduce intake temperature.
