Description
The COBB high flow filter for your Focus ST250 or RS Mk3 is designed to permit very high flow rates, minimise restrictions, maximize filtration and provide a long life filter. It uses proprietary woven cotton and metal mesh with a precision moulded rubber base. It is designed as a filter replacement and drops directly into your OEM airbox. With the dual-cone design, one can enjoy the turbo sound when air is discharged.
