Hey Dragon,
On my 01 Z06, I changed plugs several times and then redynoed. Never found any improvement over the stock, original plugs, even when they were wearing a black oil coating. Mine burned a qt/1K miles.
No more hp; no improvment in ET. I concluded changing plugs wasn't worth the time.
So unless you have a good reason to replace the stock plug at all, might just as well keep the original Denso.
I'm running original Denso in my 02 at 26K miles.

I'm about to hit 40k on my 03. Its starting to run a little sluggish and I figured since I'm pulling the plugs to put headers on i might as well drop a new set in. Where can I get these TR 55s?

TR55 in mine. No issues with the OEMs. Just doing the normal maintenance made me change them. I do need some wires and socks when I get back as I don't want to melt one on a header. Take care brother!

Try sparkplugs.com...I hear they have the best prices plus you can get all the info you need on what plug is best for you and what gap to set it at!
Or, you can go to NGKSparkplugs.com and get basicly the same info

BTW i used Magnecor KV85 wires and it does seem smoother maybe just wishful thinking though.
