How do these plugs look to you?

Drakos · 08-22-2010, 05:38 PM

I was getting some long cranking but very intermitent. The car ran a little rough on idle. Some days it was fine and some days I get a 2-3 second crank. I just put in some fuel system cleaner and changed out the spark plugs. I am trying to be as optimistic as I can hoping for it not to be the HPFP

The car does seem to be running smoother and right after I popped in the plugs, the car started up quickly. Take a look at the plugs. Did I changed them out prematurely? The car has 24000 KMS on it running JB3 from 500 Kms.

Those don't look too bad. Not to the point where it would foul.

They are still brand new.

They look brand new, very little erosion of the electrode.

Here's a site that may help with some pics of various plug ends:

Yep, i agree with everyone.
they look really good.
The electrodes look great with sharp edges still.

They are a little darker in color than mine were when I changed them. Maybe carbon build up. Do you have a Oil catch can? Running a tune will cause more blow by and more oil into the intake if you don't have a occ. Over all they look fine but you may consider an occ because pics I have seen were spark plugs start to get black and build carbon usually have very dirty intake valves. Just my .02 , good luck.
