Sorry, hate to jump in but this is connected, what is the spark
plug wire again. I know I’VE ASKED before and made a mental copy in
duplicate of the answer, but damn if I didn’t lose both copies.
Humbly with only mild mental loss.

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 ?........

The Iridum plugs are not the old
BUR series I used to use. I'll have to get that number for you. I
pulled them out of the Renesis crate engines I bought so I assume they are the
standard plugs used in the RX-8 car. They look similar to the old style
plugs with adjustable gaps but the electrodes are extreamly fine wire.
Very expensive (so I'm told) and fragile looking but they work
great.
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’s 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.
