This cold air intake system is engineered specifically for some Ford F150 V8 5.0L models, and includes a larger than stock fresh air scoop behind the front grill to increase airflow to the high-performance enclosed air box filter assembly. A high-density polyethylene (HDPE) rotationally-molded tube helps increase the volume of airflow to your engine, and provides a guaranteed increase in horsepower and torque. The included washable, reusable High-Flow Air Filter features oiled cotton filter media, and the oversized, conical design allows you to go up to 100,000 miles between filter services under normal highway driving conditions. An enclosed air box design helps protect the filter and inlet air from the heat of the engine bay, and allows for quick access to the filter. The entire system can typically be installed in less than 60 minutes. Some intakes are not legal for sale or use on any pollution controlled motor vehicle in California. See the product specifications for CARB status on each part for a specific vehicle.
