Well I am double checking with the NGK tech Mon, but if you check their website http://www.ngksparkplugs.com/ and search for plugs on our cars, you'll find they only have one listed. The Laser Cut Platinum.

I don't think NGK has ever "technically" recommended the regular TR55. GM calls for a long-life plug, therefore NGK only recommends a long-life plug. That doesn't mean the copper TR55 is a bad plug, as evidenced by many users.
If you're hell bent finding a different plug, many on the vette forums have had good luck with AC Rapidfires (not to be confused with the AC Delco platinum junk from the factory). So you might wanna give that a shot.

I've been using the $2 NGK TR55s at .050 for over two years now with no problems at all, in fact I cant beleive how good its running on them lately. I just matched my best time from last year again earlier today too on the same set of NGK plugs that were in there from last season. I'm not buying any plugs over $10 each again anytime soon

One of the first things I did was replace the AC Delco (tips fell off) with NGK Tr-55's (along with new wires) and still had a miss. One day I was screwing around and regapped my plugs to .50 (were at .58) and what do ya know no more miss. So just make sure they are gapped correctly and I dont think you will have any problems.
BTW....of course summit and NGK want you to buy their more expensive plugs becasue that = more money for them!!
