8mm Olds 55/72 / Buick

The 8mm Olds 55/72 / Buick spark plug wire set is engineered for classic American V8 engines that demand reliable ignition performance. This Spiro-Pro spiral core wire set is designed for vintage Oldsmobile and Buick platforms where original equipment specifications call for 8mm diameter conductors. Whether you're restoring a classic muscle car or maintaining a treasured collector's vehicle, this wire set delivers the ignition consistency that separates a well-running engine from one prone to misfires and rough idle.

Constructed with spiral core technology, this 8mm wire set features superior EMI (electromagnetic interference) suppression compared to solid-core alternatives, critical for engine management systems in vehicles from the 1950s through early 1970s. The red insulation jacket provides both visual identification and UV resistance, ensuring durability in engine bay conditions. Straight plug boots with socket-style connections interface directly with factory-specification spark plug terminals, while the complete V8 kit configuration means all eight cylinders are covered in one comprehensive package. The spiral core design reduces capacitive reactance while maintaining consistent voltage delivery across the full firing range.

This wire set is ideal for Oldsmobile and Buick V8 owners performing tune-ups, rebuilds, or routine maintenance on mid-century American classics. Socket-style boots ensure compatibility with standard spark plug terminals found on original and reproduction ignition components. The 10 x 3 x 11.6 inch packaging accommodates standard under-hood routing for V8 configurations, and the complete kit simplifies installation by eliminating the need to source individual wires. Proper spark plug wire selection is fundamental to maintaining combustion stability, fuel economy, and cold-start reliability in carbureted and early fuel-injected V8 engines.
