a stock like plug you could try is one range colder version of stock plug PFR7B NGK laser platinums
guess you could regap them since i don't think they are side fire..
seems like only jeff doyle and a few others run them....<ul><li><a href="https://forums.audiworld.com/s4/msgs/2242888.phtml">https://forums.audiworld.com/s4/msgs/2242888.phtml</a</li></ul>

I agree - check other things, including mixture (lean/rich)
I've run those plugs for 6 years with MTM, running boost up to 25 PSI and never had a misfire under load (idle, yes).
I have over 25k on the current set and had over 35k on the last set.
