Coil Wire - Red 12in HEI/HEI

The QUICKCAR Racing Products Coil Wire – Red 12in HEI/HEI is a premium ignition coil wire engineered for high-performance racing engines and marine applications requiring reliable spark delivery. Built with a 11.5mm spiral core and durable sleeved construction, this 12-inch coil wire manages high voltage without signal loss, making it the standard choice for engine builders working with HEI ignition systems seeking consistent cold starts and clean idle in demanding conditions.

The spiral core design suppresses electromagnetic interference while the thick sleeving protects against abrasion and heat exposure common in tight engine compartments. At 12 inches in length, this wire accommodates most distributor-to-coil configurations without requiring splices or extensions. The HEI style terminal provides a secure, low-resistance connection to both coil packs and distributor caps, critical for maintaining voltage at the spark plug under full throttle operation. The vibrant red jacket aids in visual engine bay identification during maintenance and troubleshooting.

This coil wire is designed for serious racers, engine restorers, and performance boat builders who cannot tolerate voltage drop or arcing. QUICKCAR Racing Products has established itself in the high-performance market for precision ignition components. Whether you're tuning a street engine, prepping for track events, or maintaining a marine powerplant, a quality coil wire is non-negotiable—it's one of the few ignition components that directly affects starting reliability, idle quality, and peak RPM performance.
