It has become apparent to me that we need cold heat range plus for our higher boost applications and I was wondering what some of you other guys are running part number wise to get a colder plug for our cars? I've called several people and gotten some part numbers But none of them seem to be available in my area from my sources so what do the big dogs run for Plugs?

Currently I run NGK TR5-1, stock # 7060. I have them gapped at .030". I also use a Plasma Booster for increased spark energy.

hmmm, a plasma booster? that sounds like a fun thing to have!

i was just about to post this same question. my vortech kit, will be here tomorow. and i am wondering what plugs i should run. as far as i know, the vortech kit, doesnt come with plugs??

The NGK-2315 are 1 stage colder than the stock SRT ones, and 2 stages colder than the 5.7 ones. The NGK-2314 are 1 stage colder than the 5.7L ones. I'd suggest using those for nitrous or supercharged HEMIs. CMJ, if you need NGK or any more info, I can set you up with pricing through our wholesale division, just shoot me a PM.

That is a two step colder plug. IMO you do not need such a cold plug.

**lou1355** · 07-11-2008, 12:46 AM

two ranges colder than oem ngk iridiums
ltr7ix-11 ngk-6510
Iridium IX plug, 14mm, 25mm reach, 5/8" hex, tapered seat, resistor, fine wire (0.6mm) iridium center electrode, tapered cut ground electrode, .044" gap

You need a special socket for install/removal of these plugs, I can't remember where I got mine, but i think sparkplugs.com had it.

so wouldnt the NGK-2314 be the stock rated plug for the SRT's?? and then with a FI SRT, we should run the NGK-2315??
