hks s40g??

Joe, if the stockers are 7s like you showed in the code, then get heat range 8. That's pretty standard/simple. Were you asking something else? I assume you can toss in some NGK BPR8ES, BR8ES, or BPR8EIX (iridium).

According to the IX Tech Manual, the IX plugs are a long reach design for lower combustion chamber temps. I think Ralliart makes a #9 racing platinum/iridium for the IX. At least they list it.

Not cheap though:

I think that price is for 2, ouch!
