Everybody uses b8egv or b9egv's use the 8s in NA and 9's in turbo or heavily ported cars.
You need to use a specially ground down spark plug tool to get them in and out, but that's what I'd be using.

[Kusanagi]

RE9B-T & RE7C-L for RX8

The same model no. for NGK and Denso.

T stands for trailing and L for Leading plug.

i found the egv's to foul up and missfire a bit after 8 to 10 thousand km. other than that no issue with them. ive been running the BUR9EQ since my cosmo engine havent had any dramas so far.

what the price difference these days james? and to your knowledge what are the benefits of the egv's over the bur9eq's?

some people also prefer ev's over egv's, anyone know why??

figure due to your work place james you would be checking this sort of thing out on a regular basis- i assume you would have a much better idea of what works and what don't from various sources. thanks.
