Those AR103's that ZZP sells are fine with the cutback electrode and nickle plating. I ran a set right after my cam install. For $13 over the regular 103's seemed like a good deal. I did cut back an old set of 104s and they turned out looking ok.

I saw that some previous 103 people have switched to Champion RS12YC plugs, so I gave them a shot. Apparently they are a better quality plug, lasts longer, and are a heat range between the 104 and 103s. I've only had them in for about 3k miles so far and seem to be holding up, but for me it's a little early to tell. I know Fastgs88 runs these in his 11 sec regal. We will see.
