darsdoug Posted October 11, 2021 Share Posted October 11, 2021 I bought some NGK BKR6EGP iridium spark plugs. Will those work well in my 30+ yr. old ej22? They all appear to be pre-gapped at .037 in. Link to comment Share on other sites More sharing options...

1 Lucky Texan Posted October 12, 2021 Share Posted October 12, 2021 see what alternate plugs are recommended by NGK at their website....? Link to comment Share on other sites More sharing options...
heartless Posted October 12, 2021 Share Posted October 12, 2021 totally unnecessary in an EJ22 - best plug for those is basic copper core NGK the iridium plugs are spec'ced for certain models, but they would be MUCH newer than anything with an EJ22 in it.

GeneralDisorder Posted October 13, 2021 Share Posted October 13, 2021 Just get cheap NGK plugs and gap them at 25. They will put less stress on the ignition system and last longer with a smaller gap. GD 1 1 Link to comment Share on other sites More sharing options...

They all appear to be pre-gapped at .037 in. They're so easy to replace in that engine, use the correct NGK recommended plug. Link to comment Share on other sites More sharing options...
