Spark Plug Wire Set, 7mm, 1963–66 Buick Riviera 401/425ci

Replacement spark plug wire set for 1963–66 Buick Riviera with 401ci or 425ci V8 engines

This 7mm spark plug wire set is designed for 1963–66 Buick Riviera models equipped with the 401ci or 425ci V8 engine. It replaces deteriorated ignition leads that can contribute to misfires, rough operation and unreliable ignition performance. The replacement wires carry spark from the distributor to the engine’s spark plugs and are intended for use with the listed Buick V8 applications. Retaining the original wire routing and separators helps protect the leads from exhaust heat and moving components.
