Plugs are gapped from factory and are already set. If your backfiring most likely the cap carbon is gone, worn or the cap has arc tracks causing this. Have seen the rotors have a small crack also causing this. There's 2 sets of plugs to use also. Non platinum and the platinum. Cost is the difference.
