Coil Wire - Red 48in HEI/HEI

The Coil Wire - Red 48in HEI/HEI from QUICKCAR RACING PRODUCTS is a precision ignition harness engineered for high-performance engines running HEI (High Energy Ignition) distributors. This 48-inch coil wire is purpose-built for racers, engine builders, and automotive enthusiasts who demand reliable spark delivery under extreme conditions. Whether you're tuning a street performance build or competing on the track, a quality coil wire is critical to maintaining consistent ignition timing and preventing misfire—especially at high RPM where factory wiring often fails.

QUICKCAR Racing Products manufactures this coil wire with high-quality insulation and shielding to minimize electromagnetic interference and cross-firing between cylinders. The 48-inch length accommodates a wide range of engine bay layouts, providing the flexibility needed for custom installations, engine swaps, and performance relocations. The red exterior identifies it clearly on the bench and under the hood, while the robust construction resists heat, vibration, and fuel exposure—common hazards in modified and racing environments. Proper coil wire routing and secure connections are essential; a loose or damaged wire can result in spark scatter, performance loss, and hard-start conditions.

This coil wire is ideal for small-block and big-block engine builds using HEI distributor systems, including Chevrolet, Pontiac, Oldsmobile, and Buick applications. Installation is straightforward: disconnect the old wire, connect the new QUICKCAR coil wire from the coil tower to the distributor cap, and secure routing away from headers and moving parts. The 48-inch specification works well for most underhood configurations, though longer or custom runs may require splicing or extension. Builders and mechanics appreciate QUICKCAR's reputation for reliable racing components; this wire is a cost-effective upgrade that pays dividends in ignition reliability and engine stability.
