230 engine, SN T334, two of the six spark plugs had an extension on the plug as shown in the photo. The bottom piece has no electrode. The plug is a normal Champion J11 and the screw-on piece just has a small hole to let the spark out. Never seen an extension on a plug before. Kinda funny and wondering how these work.
