JE Pistons for Ford Focus Zetec/SVT/ST170

Note: JE Pistons notes the compression numbers based on using a thicker head gasket than stock. A factory head gasket would have higher compression numbers. It would be necessary to purchase a thicker cometic head gasket of .040 to obtain the compression numbers noted by JE Pistons. The SVTF would require an even thicker gasket too.
