Default Spark Plug for H/C 99 suggestions...

What plugs should I be running? I saw an article awhile back that stated per extra 100HP you should go 1 temperature grade lower... Is the 100RWHP or 100 Crank HP?

I run the cheapest autozone plug and i'm fine. Unless you're running a power adder Im thinkin the stock heat range is best..
