OEM Honda plugs are Denso Iridium plugs, you can order them on ebay or from Honda, they have to be iridium. 35k? OEM plugs last you till 100k miles, you don't need to change it unless something is missing that your not telling us.

Honda part# 98079-571BH
This plug is tailored specifically for the S2000, by NGK.
Gapped to exact spec, THEN platinum coated. This plug can only be bought from HONDA. NOWHERE ELSE.
Adjusting the gap on a platinum plug can fracture the coating and cause the plug to fail.
Even if you get the correct NGK part number, they are not the right gap. Go ahead and check for yourself.

Can you put in the standard copper NGK BKR6E? All 3 of my other 4 cylinders run those so that would be super convenient for me seeing as I have 8 of them in the garage. I believe thats what they run in type R's

I just changed the OEM platinum plugs on my 2003 G35 with 65K miles because a recent UOA showed fuel dilution and low flashpoint. The plugs were pretty well shot (down to nubs) and one coil and plug came out soaked with oil. I had to replace the valve cover just to replace the hardened/defective o-ring seal for that spark plug tube.
Recommendation? Check your plugs before the manufacturer's drivetrain warranty is over. I wish I had. And, as Billman stated, use the Honda OEM plug. The proper gap is critical and will allow for complete combustion. Fuel dilution ruins your engine oil very quickly too.
