i just switched from autolite platnium to ngk 1 step colder and when i pulled out the autolites i noticed a white substance on the plug and a little red or orange near the bottom of the plug what do these colors mean i've heard that orange or redish is just a chemical burn

oh and the autolites where gapped at 39 and i gapped the ngk at 38 since i dropped pulley size. does this sound right?

almost looked like white powder but not powder

 

i have a similar setup to you and keep my ngk irridiums (1 step colder) at factory gap (.35)

 

i thougt factory was .40

 

for platinums

irridiums showed .35

 

oh well what about the plugs i have i re gapped them at .35 seems to be running pretty good..but what about the white...i heard white means too lean which i doubt its that with the stage 2 tune or too hot...which 1 step colder should take care of that right?

 

can someone please help me out here

and i know have the one step colder copper..shouild they still be gapped at .35????? any one please help give me a range to be in or someothing or someone that is running these pllugs in a simialer set up to mine

 

if .35 gap is fine with your irridiums then they are fine with copper.

If your running too lean no plug in the world will save you. It just supresses detonation a bit and helps.

 

and i understand that but do you really think thats the case the car runs great...could the white just mean too hot

 

im not understanding the "white"

 

can you upload a pic of the plug so i can see... multiple readings can be done by looking at the plug..i need to see the coloration of the white.. where it is.. how it fits.. and the rest

 

i pulled mine last night because my car seems to be bogging down a bit, mine were white as well, almost a chalky looking white

 

Yeah, you need to post a pic of the plug if you want it read, a description really doesn't help.

 

yea thats how mine where almost the porcielan part looked fine a little brown and black actually a little orange too... but no i can't uplaod pics...i'm on a gm stage 2 tune tho i highly doubt its lean unless my catless downpipe is effecting it like i said tho she runs fine no problems

 

nod.. clearity is a must.. threads and arch..





look like either one?

 

any modification to the exhaust to help it breathe better will lean it out some.

 

no bogging either...i don't know i'm probably over reacting....its probably just too hot

would that actually hust the car tho or just the plugs

no i looked at all those already and what i got from them was too hot or too lean...so thats why i'm here really dosen't look like any of them tho.

 

id really need to see a log of your engine before "helping" you. If you have hptuners or some sort of ODB2 logger i can help.

Otherwise i suggest sticking to the plugs for now.

 

its there.. you just cant see it... bust out a magnifine glass and start reading

 

well actually on the second ne the porcielan looks close to how mine was btu the ark what almost a chalky white...but didn't fall off like chalk when i topunched them

 

overheated and running rich if it was dark+chalky ark

 

well here's a pict of mine, even though it's blury as hell and you prolly can't see anything

u might actually be too lean....

you are too hot tho, need a more angled shot

edit: omw home, hopefully someone else can give their advice

 

i'll try to get a better one tonight.. I was told to go with the NGK Bkr7e 1step colder, does that soudn right?

 

yes those are the right plugs.
from what i can see it looks like the plugs from my car when i had stage 2. hot and just a bit lean w0t.

 

this look like the right one to you, http://cgi.ebay.com/ebaymotors/NGK-R...spagenameZWD1V

Or you know of a better place to pick them up at? Looks like autozone and advanced auto dont carry them

nevermind, i picked up these (1 step colder) http://www.zzperformance.com/cobalt_...ts1.php?id=490
