Which plugs - Iridium or NGK Sevens ?

As above, on a modded Scoob (01 WRX) what would you use. Currently have std 6's.

Did a search, but found both NGK Iridium and NGK 7 plugs recommended.

What are you all using folks ?

I would use NGK PFR 7B every time at medium spec. I have first hand experience of Denso Iridium breaking up at high EGT. Others had a similar problem around the same time.

Thanks v much Harvey.

I understand NGK also do Iridium plugs. Are they any better than the Densos ?
Otherwise, will just go for the 7s.

i was advised best sticking with the ngk7's,as the iridiums can break up at high temp as harvey said in previous post
