I use the Rapid Fire 4's from AC Delco. Gapped them to .038-.040 if I remember right. They make a new version and an old version. Get the older version if you can. I went to Oreillys and they had 8 of each so they brought in another 16 and most were actually the old version so worked out good. NGK makes good plugs too. You'll be in the 7 heat range. If your from STL your only about 15 mins from me. Where you normally boat?

Use the same plugs that you were. Stock plugs are AC MR43T or the NGK BR6FS.

We boat all over the place..mostly lately we just go to LOTO..but we do boat on the Mississippi..we have friends with house boats up there. We use to go to Carlyle lake all the time, but it got really boring after a while..where you boat?

We have a place in harbor light bay on Carlyle. Also go to Kaskaskia a lot. We try to make trips to Bull shoals, table rock, or LOTO at least once a year

NGK V Power racing plugs. Never had a problem with these plugs in a 650HP 502 with Dart Heads.

Young Performance

Use NGK BR6FS as mentioned.
