AEM'S WRX & STI Short Ram Intake features a CNC mandrel-bent 6061 aluminum intake tube, tuned in length and diameter for maximum power gains. All of AEM's intake brackets and fittings are tig-welded for strength and perfect fitment. Finally, each AEM intake is powder coated or polished for looks and resilience. The AEM Short Ram Intake for the WRX & STI uses the new lightweight dry-flow cotton/gauze filter designed to make additional power and not require oiling. AEM's WRX & STI intake is CARB approved for older models, and pending exemption for 2005+ cars. All necessary hardware and detailed instructions are included to simplify installation.
