   Tracy and Group,

         = After more searching I find that the "Denso" IRT01-31 is

listed as the "Trailing plug" and the "Denso" IRL01-27 is the

"Leading Plug" for an 2005 = RX8.........Tracy are those the plugs

you have in your engine currently  with = over 250 hours ?........

I think that would be the Denso IRT01-31; about $35.00 = each.  They apparently use iridium for both electrodes.  But if they last = 10 times as long, it=E2=80=99s worth it.

I have found that on the standard B9EGV the ground electrode = erodes and the gap gets wider.  Having an iridium center electrode may not improve the lifetime; although they are only about $1.50 more than the standard.
