Coil Wire - Blk 12in HEI/Socket

The Coil Wire - Blk 12in HEI/Socket from QUICKCAR RACING PRODUCTS is a precision ignition system component designed for high-performance and racing applications where reliable spark delivery is non-negotiable. Built for vintage muscle cars, street rods, and purpose-built race engines running HEI distributors, this 12-inch coil wire bridges the critical gap between your ignition coil and distributor cap socket. Whether you're tuning a carbureted small-block or managing multi-point EFI on a modern swap, a quality coil wire eliminates the weak link in spark timing consistency that can cost you horsepower and throttle response.

This coil wire features a black insulation jacket rated for heat and electromagnetic shielding, protecting the high-voltage signal from cross-talk and voltage degradation under sustained engine load. The 12-inch length accommodates most traditional engine bay layouts while the HEI-compatible socket terminal ensures a clean, corrosion-resistant connection to standard HEI distributor caps. The wire's construction prioritizes low capacitance and high dielectric strength—essential properties that prevent signal loss and arcing, particularly critical when running aggressive ignition timing curves or solid-core plug wires on all eight cylinders. At just 0.28 lbs, it integrates seamlessly into any ignition harness without adding unnecessary bulk.

Mechanics and engine builders favor QUICKCAR coil wires for restoration projects, street performance builds, and competition platforms where ignition reliability directly impacts launch consistency and mid-range torque delivery. The black finish blends cleanly in traditional engine bays, while the HEI socket compatibility makes replacement straightforward on any distributor-equipped platform from the 1970s through today. This coil wire is an ideal upgrade when refreshing aging ignition systems or building a fresh high-output combination—pairing it with quality plug wires, a solid coil, and fresh plugs creates a foundation for spark that won't betray you at the track or the strip.
