OK, I've been searching this topic for about 2 days now and have found some useful info, but still haven't found the right answers.

I haven't been getting the best results with the ones I'm using. During all the searching, I've pretty much gathered that champions are shit. Come to find out, thats what I have in my car. I check'em regularly to keep an eye on conditions in the cumbustion chamber. Some times they look good, other times...not so good. I'm still relatively new to the boosted world so maybe someone with a better trained eye can see something I can't. This was pulled from #6, and all plugs look about the same.

I think maybe I could use a range colder. What do some of you think?
Also,I want to try copper, as I've read they respond well in boosted aplications, and iridiums are ~13.99~ a piece, but I've been all over this damn town and can't seem to find anyone that carries copper.
Now, does NGK make copper plugs? If so, can someone give me a pn w/ correct heat range, 1 or maybe 2 step colder than stock. FYI the champions I've been running(in pic) are 1 step colder. Thanx for all your help, let me know if you might need additional info on my set-up to determine a good plug for me.

NGK makes coppers all right, can get them off most of the sponsors on this board. I like the coppers because they're cheaper and it forces you to change them more. This way you can keep an eye on what's happening. Part Number is BCPR6E. I don't know about anyone else but I have run 18psi with no problems on the standard plug. Haven't had to go a step colder yet.
