Rotaries, because of their oil injection, do tend to fowl plugs if not driven spiritedly often enough. But yeah, 25k miles is probably about right. I had never priced out the RX-8 plugs, and assumed they'd be about $48 for the set, like the RX-7. Nope, the set of four plugs will run $103.02. Wires probably should be replaced every-other plug change. The factory OEM NGK wires run $42.69 for the set. The coils are pretty robust, and only need replaced if they fail, they're $43.33 each.

So...
$103.02 every 25k miles
$145.71 at 50k
$319.03 if you need to replace all 4 coils with plugs and wires
