What do you guys think? It's all white (The ground electrode). Just want another opinion really. Thanks guys.

These are BKR6E's (stock heat range), gapped at "0.034

I'm not 100% on this either, but the car seems to run very smooth for a few seconds, then rough, then smooth, almost like a misfire.

White usually means the plug heat range is too hot for the given application, but I find that hard to believe since you are basically GMS2. The stock heat range should be fine for your setup, but all cars react differently to mods, and such.

Does the tip of the electrode look worn or damaged at all?

How many miles are on the plugs?

That's definitely lean. I'd invest in a wideband and see what your AFR's are...

Right, that's what I was thinking. I am just GMS2 and full bolt-ons.

What about the gap? Would this cause the "misfire feeling"?

There are about 500 miles on the plugs, however my last plugs were in there for 3,000 miles and looked exactly the same.

And those general guides for plugs never seem to be close enough to mine I always second guess.

AFR's should be spot-on. I just had my exhaust installed less than a month ago by ZZP and Tim checked everything out himself and said it is all good. He checked at idle, cruising, and WOT.

Do you have an interceptor, or anyway of logging the car?

The gap of the plug can cause acceleration issues. Although, 0.034" is a pretty decent gap for a GMS2 car. I ran the stock gap on my car (0.035") all the way to GMS3. I didnt experience spark blowout or acceleration issues until I bolted on my H62 blower. I lowered the gap to 0.032", and havent had a problem since.

Go pick up some 1-step colder plugs, and see if helps. You should have a greyish to light tan electrode when you are running the correct heat range plug.

Sadly no, I don't.

Should I close the gap to 0.032" and see what happens?

I can pick some 1-step colder plugs by tomorrow, and what would I gap those to, 0.032" also?

Try 0.033" first, and go from there. Remember you want the largest gap possible w/o spark blowout (not saying that you do have spark blowout). See if closing the gap clears up your acceleration issues.

I would def look into picking up 1-step colder plugs up though. Let me know how you make out.

Close gap to. 032. If u still have a issue go to. 030 if u still have a issue ger 1 step colder and gap them at. 032 if its still doing it. Abd all plugs have the white then invest in a tune

Will do! Thank you sir(s), I will post the findings soon. I'll go close the gap now.

That plug doesn't look like it is in bad shape to me. In fact, it looks like it is burning just fine but running a bit rich, which would be normal for a GMS2 car.

Closed it to 0.032", seems to run a bit more smooth.

0.030" is way too small for a GMS2 car, or for any LSJ blower setup really. I would only suggest gapping that low if he was experiencing spark blowout with a 0.032" or 0.031" gap. A GMS2 car is not flowing enough air to need that small of a gap.

Good to hear man. Your plugs are rather new as well. Put some more miles on them, and check them again.

It's hard to really tell from the pic, but are they more of a greyish white color? If so, your plugs are fine (just new). If they are "pure" white that would be a clear indication that they are too hot.

You think 0.032" is too small then? Seems strange but before I changed them I never had this problem (I ran stock plugs at 0.038"), but I was told that for the mods, the gap should be smaller.

Staged07SS

iTrader: (25)

For a GMS2 car? Yes, it's a little small.

When I was still running the M62, and straight GMS3 setup (76mm pulley, intake, & full exhaust) I ran the stock gap of 0.035" (stock gap for my car from the factory) w/o any issues.

I did not close the gap until I started to experience spark blowout. Spark blowout feels like you are hitting the rev limiter, but happens well before it sometimes. When I bolted the H62 on (was flowing more air), I noticed spark blowout around 5500 rpm on a cool night. I tested every gap from 0.035" - 0.032" until I chased the spark blowout away, haha.

But hey, every car reacts differently. If yours seems to be running better with the smaller gap then keep it there. Just monitor your plugs after a little more driving.

Haha.. my car must be less picky than everyone elses... I gap them at .032... then don't check them for 15-18k .. and they've opened to .040.. and i don't experience blow-out..

staged, ive experienced this issue first hand . gms kits are rich so if he was happening to have spark blowout either because of the richness or the amount of air then id gap down to a .031, and so forth to a .030 ive seen good results with that gap. Also if he had hptuners he could expand dwell time, but thats not the point. The point i know your making is a gmstg2 kit will not produce enough boost to create a spark blowout situation. Well it can happen and i see your point im just giving my 2 cents lol

plugs look fine to me, if they start looking like this, then be worried.

I hear ya man, and I know you know your ****, but you want the largest gap possible to optimize the A/F mixture (which I'm sure you know). Too small of a gap on a car that isnt producing the power nor the air flow isnt the best solution.

I know the GMS2 tunes run rich (10.8 cmnd A/F ratio on most), but if he was running rich enough to cause acceleration issues it would be evident on the plugs (black carbon covered electrode, etc.). After looking at his plugs a few times they seem to actually be ok. They are fairly new, and look like they are just starting to burn in so to say. They look to be more of a greyish color than a pure white color. The greyish color is an indication that they are the right heat range for his particular setup. As long as they dont turn pure white, or blistered looking he should be ok with those plugs.

put them in some soapy water and itll fix it.....











im just kidding bro, i know staged, and i of course know that you know your shiz to lol.... lmao that comment actually made me feel like i am a idiot.. i dunno why but made my iq go down to like 1 instead of 3 lmao ha ha ha.. His plugs do look newish since the insulator for the electrode is still white, bu only thing that gets me is his the idle issue, i wonder if his t.b is causing it or the tune. or something else.
