Prolly a stupid question but..I just change my plugs last week. Right before 40k miles because I'm about to get tuned. Is this what normal used plugs look like?









This didn't exactly look right to me..

 

they look ok to me.

they have some miles on them for sure, but nothing glaring

 

They look overheated with the brown on the porcelain

 

looks a touch on the lean side. definatly hot. hense the white on them. I have a set I pulled out after 47000 miles was running a lean code had a hole wore in on the vacuum line to the fuel regulator i will take a few picks for you.

 

Looks like things may be a bit lean as others have mentioned here, otherwise not bad.

 

These had 47000 miles on them I belive. Had a lean code prior to the change fix the lean problem replaced plugs. These are only a 7 heat range where yours are a hotter 8 range might be why there a little whiter.

 

8 is colder than 7. Ngk is higher numbers= colder plugs

 

Looks fine to me over the internet. The "dusting" has nothing to do with heat unless it's so lean there are no deposits at all. Some deposits like you have are normal.

You have to look at the band on the strap to determine the actual heat. Which nobody can see from those photos, so ignore the people saying it's running too hot.

 

This.

 

they just look like plugs that needed to be changed.

i bet the car feels a little better now. colder plugs properly gapped always feel good.
