This is the NGK BPR6EFS spark plug supplied under the Quicksilver number 33-816336Q. It arrives pre-gapped to the engine maker's specification, and the maker still recommends checking the gap before it goes in. The insulator is pure alumina silicate ceramic, which the maker credits with strength. A ribbed suppressor seal extends resistance, and a triple seal helps prevent leakage.
Our take
The pure alumina silicate ceramic insulator is the feature to note, since the maker ties it to strength. The plug comes pre-gapped, yet the maker still advises checking the gap before fitting, so do that before it goes in.
