1966 427 Braided Spark Plug Wire Set Date Coded 3-Q-65 with Radio 1320-653
GM stamped these spark plug wires with quarter-year codes back in the day, and this set nails that 3-Q-65 marking just like the factory did. Built from original GM blueprints, cut to the exact lengths, and dressed with the right boots and factory scripts, these wires don’t just make your big-block run right, they make your engine bay look like it just rolled out of St. Louis. If you’re chasing factory-correct points or just want to do your Corvette justice, this is the kind of detail that tells the world you didn’t cut corners. And yes, they’re designed for cars with radios, so you can blast your tunes without spark interference ruining the vibe.
