OEM plugs keep on breaking and causing misfires. Which plugs are needed to prevent this?

Plugs keep on breaking when in 5th/6th gear and pushing foot down at cruising speeds when at 60mph/2,000-2,500rpm!

I will take a look anyway; I have already ordered the NGK 5992 and N20 sparks, but was wondering if there's another also "proven" option. Plugs that can handle 21-22 PSI of boost.

i think so far the n20 plugs seem to be it for the people running 20 psi. .18-.20 gap

I think your problem is probably the gap. I run NGK 95770 plugs in my Wife's N55 gapped at .022 and the same plug in my N54 at .018 with no issues in either vehicle.
