I ran my stock plugs up until I pullied down to a 73mm pulley on my H62 blower & GMS3 tune. Only then did I notice the stock heat range was to hot for my application.
Stock plugs are fine with GMS2, and your mods. Just adjust the gap if you start to experience spark blowout.

No.
BKR7E are one step cooler copper plugs.
Stock plugs are heat range 6, and are either platnium or iridium (depending on year).
What I was trying to say is it will be silly for you to change your plugs (unless they have a lot of miles on them). The stock plugs will be fine for your setup.

It's a 2006, if that helps.
Yeah, I am due for some new plugs though.

I know that 05's & 06's (along with early model 07's) came stock with platnium NGK plugs.
Theoretically, you want the largest gap without problems like it breaking up in high RPMs.

My car came from the factory with the iridium plugs you listed, but they were gapped at 0.035". That has always been the sweet spot plug gap for most lsj's. It is still large enough to promote a strong spark, but small enough to avoid spark blowout once you start to pulley down.
I didnt start experiencing spark blowout at that gap until I pullied down to a 74mm pulley, and finally a 73mm pulley. I now run one step cooler plugs gapped at 0.032".
Unfortunately that plug is still a dealer only item so you would use the platinum version which is PFR6T-10G stock# 5542

I thought i've heard don't gap the bkr7e's before is this true??
when i got my ottp stg2 kit it came with these plugs and i was under the impression that they come correctly gapped so i didn't mess with them. car runs fine, only it misses a little bit every here and there in idle.

All depends on the car & supporting mods.
The more air you bring in, the more chances of having spark blowout when running a larger gap.

Always check the gap yourself, and adjust accordingly.
Heres all the information from Graham @ NX and Brandon with NGK..
NGK aside from being the plugs I use personally are the OEM distributor for plugs on these cars.
Supercharged cars First
SC - The factory plug on 04-05 redlines and 05 cobaltss cars is the PFR6T-10G. They changed that to a IFR6V-10G which is the same plug but a iridium platinum plug.

So i bought NGK Iridium BKR6EIX spark plugs for my 2005 Cobalt SS Supercharged off zzp cause i had ran them in my honda before this and had no problems with idle or anything. My car only has a 3" catted downpipe and a k&n intake, i have NO injector or pulley mods, will these be fine in my car? I am not tuned for the downpipe/intake right now but mid april I'm going to zzp to get the 1.0 pcm, what should i tell them to let them know that these are in my car if need be? But last and finally, will these be fine on my setup?

okay this might be a nub question, but do our plugs need to be torqued, and if so what are the numbers?
as well could someone please recommend a plug for me, mods in sig...
Only change is instead of budget tune i've upgraded to the regular 24 psi trifecta tune.
