Airaid Intake System features the Airaid intake kit. It has been designed to fit the 2005-2009 Ford Mustang GT 4.6 liter race version. The Airaid intake systems are computer designed to give the engine maximum air flow, which means more horsepower, torque and improved performance. Every Airaid intake system is dyno tested and tuned to provide maximum performance and efficiency. By utilizing computer-aided design, Airaid intake systems offer an unmatched fit, finish and lifetime warranty. Each Airaid intake system provides superior air filtration, since it comes with an Airaid premium filter featuring exclusive filter technology. They are constructed using the finest materials available today. All Airaid premium filters utilize a hand-poured urethane body that won’t crack, curl or shrink like other rubber or plastisol units used by other competitors. Airaid's filtration performance is second to none, and at no extra cost, thanks to the combination of the proprietary material and multiple cotton gauze layers. All Airaid premium filters are 100 percent washable, reusable and feature the lifetime "no hassle" warranty.
