they are a different design, instead of surface discharge like the stock plugs they are an air gap type, like a normal piston engine. or if you prefer the Rx8 plugs are like the racing plugs except in a normal heat range.
the performance benefit is that the Rx8 plug is less prone to misfires than the stock plug

Anybody else running these? I wonder if the electrodes are prone to breaking or not? Any benefit to running them? I don't see it being to much of a difference than running regualr 9's at less than half the cost. Maybe later on I might try a pair on the dyno in the leading holes to see if there is a difference.

in a turbo car Rx8 leadings and race trailings would be good on the street.

I'm planning to change my plugs and wires once I get the fuel pump wired up and turn up the boost. I'm shooting for the 375-400whp range at around 15psi, so what leading and trailing plugs would be the best choice?

if its a street car you should run either 11's all the way around, or 11's in the trailing and 9's in the leading.
