    Does anyone know what gap i need to set my plugs to. The guy i talked to said it was 35 but he didnt even ask what engine size so im just wondering if he was right or wrong. I got a 3.4L v6. Thanks

    .44 is the gap. If you buy them from the dealer or at sparkplugs.com they are pre-gapped.

    If they are dual electrode then they dont need to be gapped.

    Thats what alot of people think, but they DO need to be gapped. The last dual electrode plugs I changed, the gap was WAY off. Its easy to re gap. Anyone who thinks that their plugs are "pre gapped" check them to be sure. Yes, 44 is the book value, but as the gap seems to grow larger over time, I have always just gapped @ 40 to 42. :)

    most spark plugs are supposedly gapped, but everyone i have seen needed to be gapped a bit more.
