These Roush cold air intake systems for the Ford F-150 are true bolt-on systems that come complete with all of the necessary hardware and install in just minutes. These intake systems include a high-flow filter that is protected from engine heat by Roush Performance's cool air dam design. The high-flow filters are washable and reusable. These kits also include a modular intake tube that will wake up even the tamest of engines because it flows up to 400 cfm more air than the factory unit. They are constructed from cross-linked, high-density polyethylene for strength and durability.
