The Autolite Copper Resistor Spark Plug assists drivers of gasoline-powered cars that rely on modern audio systems and electronic accessories while covering long-distance commuting routes. Its internal resistor helps cut down ignition noise that could interfere with radios or in-cabin electronics, which benefits vehicles used for daily travel and highway cruising. The copper core conducts heat away from the firing tip, helping the plug remain clean during varied driving speeds. With a 5/8-inch hex, it fits many service sockets, making plug changes straightforward for do-it-yourself owners and professional shops. The Autolite 3924 suits drivers who want consistent spark performance while preserving clear sound from entertainment and communication equipment.
