AEM 2005-09 Legacy GT Intake Systems are designed to produce increased horsepower and torque gains as well as better engine sound when used as a replacement for the factory airbox and air filter. This kit include an oversized AEM Dryflow synthetic washable air filter for optimum air flow, filtration, and performance while allowing easy oil-free cleaning. The AEM intake uses mandrel-bent aluminum intake tubes, powder coated heat shields, and high quality hardware designed to reduce restriction and reduce intake temperature.

The AEM cold air intake for 08-10 Subaru WRX / STi is a great way to get a cooler & denser air charge into your engine. This intake system produces estimated gains of 36 hp. AEM has designed this intake to retain the stock diameter MAF housing and features a built in air straightener to ensure the MAF sensor readings are accurate & will not cause a check engine light. This intake features a 9 inch dryflow air filter to ensure the MAF sensor does not get gummed up which is common with oiled filters. The included heat shield ensures the intake will be inducting a nice cool air charge drawn from the fender.
