I saw a "reel" on Instagram that showed how to unscrew and replace the tip on the ignition wire end with a solid core tip. They said their example is specifically for a Mopar. The replacement tips can be re-used again and again in fresh plugs. Not sure where they get them, but figured some of you guys know.
