Just pulled my plug to take a look at it and I am sure sure if it is burning ok...any help would be great. They are NGKBR8ES and mods are in my sig.

 

looks fine to me... no what crust so its not rich, not super burnt so its not lean..

when they look like this, then you should worry.




cheers!

 

Looks ok, possibly running a little lean. How many miles are on these plugs?

 

Maybe just over 1,000 miles. I was worried about how the arch part of the plug that is silver has some chip parts in the color of it.

Thanks for the link, it says that my light gray means it is normal, but does not say anything about it being light gray with chips in the gray. I can almost scrape it off with with my finger nail. Is that I sign of detnation or anything?

 

thats normal... just typical use... they will progessively get worn down and beaten up... til you have 23k then they will look like mine.

cheers!

 

Brown is good, I had race gas in my car and well the plugs wrer full of lead(white)

 

You cant check spark plugs unless you do it correctly. If you were just cruising before you pulled them they will have reached its self cleaning temps in which they will look rather lean- or cleaner than usual. This is not a correct way to check plugs. The proper way is to go out and use full boost and redline shifts and much as possible, then quickly try to remove the plugs and inspect them, this will show you if your mixture is lean or rich.

 

Those plugs look normal, their is nothing but normal wear showing, and they dont look rich or lean, just about right.

 

+1 that's the exact thing I was thinking..

 

Thats normal i took mine out only after 20 miles and they look the same way. DOnt worry about it.

 

bump.....I did go out and high boost before I pulled them but it took me a minute or two of slow driving in my neighborhood before i could pull them. I think the color of the plugs looks good, but what i am concerned about is th fact that there are some chips in the color.

left plug = 1300miles, right plug = 2200miles
