7MM Bulk Spark Plug Wire 100ft. Spool - Black

The PERTRONIX IGNITION 7MM Bulk Spark Plug Wire 100ft. Spool in black delivers reliable ignition performance for engine builders and restoration shops requiring economical, high-volume spark plug wire solutions. This 100-foot spool format provides cost-effective coverage for multiple installations, making it the preferred choice for shops handling classic car restorations, hot rod builds, and fleet maintenance projects where consistent ignition quality matters.

Built with a spiral core design, this 7mm wire maintains stock appearance while supporting modern ignition system requirements. The spiral core construction manages electromagnetic interference and heat dissipation, critical factors in dense engine compartments where wire routing runs adjacent to other electrical components. The 100-foot bulk spool format allows custom cutting and jacket termination, enabling technicians to fabricate wire sets matched precisely to their engine's specific layout and spark plug location geometry.

This product serves engine shops, restoration specialists, and serious enthusiasts who fabricate complete ignition harnesses rather than purchase pre-assembled sets. The black jacket matches original equipment appearance in vintage and modern builds alike. PERTRONIX IGNITION spark plug wire is recognized within the restoration community for maintaining compatibility with both original and contemporary ignition systems, from points-based distributors through modern computer-controlled engines.

Bulk wire spools eliminate waste compared to pre-packaged sets and reduce per-foot costs for high-volume applications. The 4.95 lb. spool provides ample material for multiple complete engine installations. Storage and handling are straightforward—the spool format prevents tangling and maintains wire conditioning during inventory management. For shops managing inventory across multiple projects, bulk spark plug wire represents both operational efficiency and material economy.
