This part is directly equivalent to the Bosch W8LCR design, which uses a deeper projection of the electrode into the combustion chamber. This was the spec for US models. If you use higher-compression pistons and are worried about piston-electrode contact, try the Euro version of this plug - W8DC, which has a smaller projection.
