Hey guys,
What spark plugs would be best in a mildly modified FTO MIVEC engine that will be used on circuit?

Thanks guys,
Those are iridium plugs though which have the benefit of longevity but is this something I need for a circuit car that will see in reality only a couple of hundred kilometers a year?
Copper is supposedly better for performance as it is a better conductor.
Additionally what about the heat range and the gapping, would I need to do anything different than what Mitsubishi advises?
And lastly, best brand?

Heat range: 7 (NGK) or 22 (Denso) for the MIVEC
Gap: 0.8mm
Brand is a matter of preference. I prefer Denso
