known:
they fit in an fc rotor housing, ie they dont stick out and hit the apex seal
they look like race plugs
unknown:
heat ranges are 6L and 7?T stock, does this correspond to the breq's?
do they work?

Renesis also has a higher compression... Might be the reason that single ground strap will work, like the colder race plugs such as NGK, or HKS.
Don't know if it will work better or not, with lower heat range, bigger flame front for the older 13B NA....

The heat #'s for FC/FD are 7L & 9T. The race plug is 11.5 (all 4) for FC/FD and is NGK but I can't tell from the picture if it has that thin peice from the side to the electrode (forget what it's called).
Well if they are Denso then they are the Iridiums @ $35ea (7's/9's) but if they are NGK's then they are the race plugs @ $26ea . The iridiums should also be a titanium grey as opposed to the copper.

Well that deoends on how you difine race plugs. They are hotter and race plugs are colder but they are basicaly the same plug, well except the RX8 plugs should be Iridiums. It looks like you have coppers and 6 heat range and the Iridiums listed for the RX8 are 7's (RE7A-L).

...whoops and RE7B-T. I can't find them for sale on sparkplugs.com allthough if you called they could get them, i'm sure. I also can't cross reference the Denso Iridiums to the NGK's which would answer you question.
