Coil Wire - Blk 36in HEI/Socket

The Coil Wire - Blk 36in HEI/Socket from QUICKCAR RACING PRODUCTS is purpose-built for high-performance ignition systems in race engines and modified street vehicles. This 36-inch spiral-core ignition wire bridges the coil pack and distributor cap socket with precision shielding, designed specifically for HEI (High Energy Ignition) distributor systems and compatible socket connections. Whether you're running a classic muscle car restomod, bracket racer, or street machine with an upgraded ignition setup, this wire delivers the electromagnetic isolation and durability needed to prevent cross-fire and maintain clean signal integrity under sustained high-RPM operation.

The 11.5mm spiral-core construction combines a robust inner conductor with a braided copper shield, effectively suppressing radio frequency interference (RFI) that can degrade ignition timing accuracy and cause misfires in competition or high-output engine environments. The black nylon sleeving protects against abrasion, oil degradation, and heat exposure while maintaining flexibility for tight engine bay routing. At 36 inches in length, this wire accommodates mid-size engine compartments with standard coil-to-distributor distances, offering sufficient reach without excess slack that could cause noise or contact with hot surfaces. The durable construction and sealed connectors ensure consistent performance across repeated heat cycles and vibration exposure typical of racing applications.

This coil wire is ideal for hot rodders, engine builders, and racers upgrading stock or aging ignition systems to maximize spark efficiency and eliminate misfire problems. Installation is straightforward—simply connect the female socket end to the coil terminal and the opposite end to the HEI distributor cap, ensuring tight connections free of corrosion. Proper routing away from plug wires, fuel lines, and exhaust manifolds will extend service life and maintain EMI shielding effectiveness. Verify your engine's coil-to-distributor spacing before purchase to confirm the 36-inch length meets your application requirements.
