Is there a reason why these "G-Power" Platinum plugs are so cheap compared the normal platinums? they're even cheaper than the coppers. $2.19 at napa for G-Power vs $2.49 for the Coppers. is there something bad about them?

If they're ok then I'll get a set

 

NGK iridium is wut u want
6 bucks a piece on eBay
better deal

 

Just stick with NGK's. They are well proven, good quality plugs. I use nothing less.
