The K&N roto-molded cold air intake system for the 2007–2009 Ford Mustang Shelby GT500 (V8 5.4L SC) uses an HDPE rotationally-molded tube to increase airflow volume and is paired with a washable, reusable oiled cotton high-flow filter. The oversized conical filter can allow up to 100,000 miles between services under normal driving, and a custom heat shield helps reduce intake air temperatures. Check CARB status for California legality; covered by K&N's warranty.
