Are they the same model plug w/ w/o gapping needed?
A non-firing plug( worse case scenario) would be filthy with gas and carbon all over the tip.
Are these plugs with adjustable prongs that gap must be set? Is so that was perfectly gapped.
The heat will make them a reddish brick like color. That's ok too.
