K here it goes...I have a Vortec S/C 93 Cobra that I've been having some ignition issues with. My original thought was “I’m just blowing out the spark because the ignition isn't hot enough“.... but then it occurred to me, I never really paid any attention to my plugs when I bought them. All I did was walk in and say "I want the TR6 NGK at 1 deg colder than stock" and then they handed me the plugs. So here’s my question, I know that 22's or 23's are generally what’s accepted as decent plugs for S/C applications, but I don't see anywhere on these plugs that suggests anything along those lines, the only thing that even resembles these numbers is in the center of the plug "right bellow where it says TR6 Vpower" is an engraving "K34R" Are these even the right plugs, are they stock temp, too hot, too cold?? Thanks in advance!
