MINI Cooper S Cylinder Head Core (was removed at dealership after pre-delivery inspection mileage for the JCW upgrade). It has been cleaned and refaced by local Machine Shop. It comes with OEM NGK spark plugs, spark plug tubes, camshaft bearing caps, valves, valve stem seals, and valve springs. It will fit Cooper and Cooper S models from 2001-2006, plus covertibles to 2008. Contact me at [email protected] for more info/photos. Jeremy
