So I'm changing spark plugs and the new ones match thread size and the threads are the same length, however where it sparks is 3/16" longer on the new ones. Is this ok? I'm guessing the old plugs are factory. 1988 four winns horizon 4.3 omc Old plug ACMR43T New plug RV15yc4 |

That is the correct Champion plug cross reference to the original AC Delco Marine plug, but I think I'd stick with the Delcos if you can easily get them. |
