is there a step colder on a/c delcos i can not get ngk's they are non locatable i have a 2.2 ecotec what plugs do i use for 15psi i need help i have tr6's stock number 4177 but there way to short
2 steps colder = LTR7IX-11
stock #6510
1 step colder = LTR6IX-11
stock #6509
I got these part numbers from ecotecforum.com
I don't think NGK's are shorter than stock.

or go to your auto store and ask for SRT-4 champion plugs

i hear terrible things about these you have any experience with them also what gap on the coppers
I have been using these for a few years now with good luck. I replace them about every 15K. They are identical to stock and Iridiums (highly recommend you run iridiums regardless of what you go with)
2 steps colder = NGKs LTR7IX-11
stock #6510
I gap em at .030"-.032"
I have ran up to 22psi with a 20G on stock ignition without spark blowout or pre-ignition so they are pretty decent in my experience

I have best luck finding them at NAPA and they always only seem to have 4
I did buy a set from autozone once too
My brother use to order them from www.sparkplug.com and they were always in his hands within a couple days so use them if you can't get them locally.

Rockauto.com has them, cheaper than sparkplugs.com
Cross reference plugs for an SRT4 neon, same sizing and any OEM plugs for that car are one step below the 2.2 eco. I'd go with something Iridium, yes they are pricey but having to change copper plugs every 5k miles or so becomes pricey and annoying.

SRT-4 plugs have the potential to damage your engine because they are too long. The NGKs we referenced are the same exact length at stock.

Get the 2 step plugs off the bat. There only like $11-15 Canadian....so must be cheaper in americatown.
