That's a great idea! How do you know when to change them, say if they have normal wear like this pic?

This is on NGK's website on how to read plugs. http://www.ngksparkplugs.com/tech_su...qs/faqread.asp

I run the stock heat range Denso IKH22 iridiums with .22 gap & Spoolinup COP. This is on an Evo 8 block with Evo 9 head running anywhere from 35-42psi.
