Make sure they are copper or if you want to pony up the cash NipponDenso Iridiums. Don't bother with NGK's Iridiums and that's rare coming from me as their other plugs are good.

For that matter Autolite has a new line of dual tip Iridium plugs. (Extremes)

Make sure to close the gap up a bit. .045 should be fine for that range.



Just out of curiosity, I'm running autolite xp104 iridium plugs right now. Those ok or should I just get the TR55? Planning on a 55 wet but may bump it up to a 75
