MSD Spark Plug Wire Set P/N:31379

Deliver a clean, reliable spark path across your classic Chevrolet or GMC's ignition system with the MSD Spark Plug Wire Set, part number 31379. This complete wire set is a direct-fit replacement for a wide range of 1966-1974 Chevrolet and 1968-1974 GMC applications, including the Chevrolet Bel Air, Biscayne, Caprice, Corvette, El Camino, Impala, Camaro, Chevelle and Monte Carlo, plus GMC and Chevrolet C-series and K-series pickups and Suburbans. See the Buyer's Guide tab for the full list of 57 applications.

• Carries the ignition charge: routes high-voltage current from the distributor to each spark plug.
• Complete set: replaces all of the plug wires at once so every cylinder runs on wiring of the same condition.
• Direct-fit: engineered as a replacement set for the listed Chevrolet and GMC applications.

Over time, ignition wires can break down internally or at the boots and connectors. Signs the wires may need replacing include misfires, rough idle, hesitation, hard starting, visible arcing in the dark, or radio interference. If worn plug wires are the cause of these symptoms, this set replaces them. Diagnose the underlying cause before replacing, as these signs can have other sources.
