Coil Wire - Blk 12in HEI/HEI

The Coil Wire - Blk 12in HEI/HEI from QUICKCAR RACING PRODUCTS is a precision ignition harness engineered for high-performance and race-spec engine builds. Designed for HEI (High Energy Ignition) distributor systems, this component bridges your coil pack and distributor cap, delivering critical spark energy with minimal signal loss. Whether you're building a street rod, weekend racer, or restoring a classic muscle car, a quality coil wire is non-negotiable for reliable engine startup and consistent combustion across all RPM ranges.

This 12-inch black coil wire features a spiral-core construction with 11.5mm diameter shielding that suppresses electromagnetic interference and cross-firing—critical in tight engine bays where multiple ignition leads run parallel. The sleeved design protects the inner conductor from heat, abrasion, and moisture, while the HEI-style terminal ensures a secure, corrosion-resistant connection at both the coil tower and distributor. QUICKCAR's specification meets OEM performance standards and is suitable for both points-based and electronic HEI systems, making it a versatile choice for carbureted or fuel-injected applications requiring dependable spark delivery.

Mechanics and engine builders rely on QUICKCAR coil wires when precision and longevity matter. The 12-inch length accommodates most distributor-forward layouts common in small-block Chevrolet, Ford, and Mopar builds, though compatibility should be verified against your specific engine platform and coil location. Installation is straightforward: route the wire away from exhaust manifolds and headers, ensure both terminals are fully seated, and verify spark consistency at idle and under load. For vintage restorations or modern race engines where ignition reliability directly impacts performance, this coil wire delivers the quality finish and electrical integrity professional tuners demand.
