This is Mercury part 8M0114747, an NGK BPR6ES standard spark plug. It arrives pre-gapped to the engine maker's specification, though checking the gap before fitting is still recommended. The insulator is alumina silicate ceramic, and a triple seal is there to help prevent leakage.
Our take
The alumina silicate ceramic insulator on this BPR6ES is meant to resist breakage and move heat well. Even though it ships pre-gapped, the maker still says to check the gap before fitting, so keep a gauge on hand.
