I am testing this idea:
Soaking the used plugs in Seafoam to remove the carbon.
It seems to work, I will try the best of the resulting plugs after resizing the gap on them tomorrow.

 

why not spray with brake cleaner and replace/

 

becuz he's gonna do exactly what he just said...TESTING an idea..in terms, broading his knowledge of what works and what doesn't..don't u luv how ppl don't read what u post carefully

 

Does that remove carbon too?
/Sounds like I might want to try soaking them in brake cleaner too....

 

put it in a large ziplock bag..



it works well...

Great idea, I just seafoamed my engine and it ran a whole lot better.

 

I think it works.
There was a lot of carbon on the bottom of the glass.
(I didn't think to take a picture of the carbon, but it covered the bottom of the glass)
My car is running good on these reused plugs, but I did gap the plugs after they were cleaned.

 

Your performance is from the gap change.

I would use one of those spark cleaners you can buy at the auto store. They lightly sand spray it.

The ceramic core is my concern.
