The Volant Pro5 closed-box air intake for 2001–2004 Ford F-150 5.4L V8 upgrades the factory intake to a sealed system that increases airflow while shielding the filter. It features a Pro5 5-layer oiled cotton gauze filter pre-oiled for immediate use and tuned for maximum flow. Included are a closed filter box, air duct, connectors and clamps; the rugged lid reduces heat soak and the kit installs in about an hour.
