Coil Wire - Blk 24in HEI/HEI

The Coil Wire - Blk 24in HEI/HEI from QUICKCAR RACING PRODUCTS is a precision ignition harness engineered for high-performance marine and racing engine applications where reliable spark delivery is critical. Whether you're running a fuel-injected outboard, a custom-built inboard engine, or a performance automotive setup, this 24-inch coil wire bridges your ignition coil to your distributor cap with the dependability that serious boaters and engine builders demand. Built to withstand the vibration, moisture, and temperature extremes of extended water operation, this wire delivers consistent electrical performance when it matters most.

This coil wire features a robust spiral core construction wrapped in a protective sleeved jacket, measuring 11.5 mm in diameter to provide superior electromagnetic shielding and noise suppression across your ignition circuit. The black finish not only resists UV degradation from prolonged sun exposure but also blends seamlessly into modern engine compartments. Both terminals are HEI-style connections, ensuring secure, corrosion-resistant contact points that won't loosen under the constant vibration of marine propulsion or racing engines. At 24 inches in length, the wire accommodates typical mid-range engine bay layouts without excess slack, minimizing electromagnetic interference and maintaining clean spark timing throughout the RPM range.

Boaters upgrading ignition systems on fuel-injected outboards, inboard conversions, and classic marine engines will find this wire an essential replacement component for maintaining peak engine efficiency and cold-start reliability. Engine builders installing or rebuilding HEI-equipped marinized V8s, inline sixes, or performance small-blocks benefit from the consistent electrical path this wire provides, especially in high-vibration environments where connection integrity directly impacts throttle response and fuel economy. Installation is straightforward: simply disconnect the old coil wire at both the coil and distributor cap, then seat the new HEI terminals firmly until you hear a click, ensuring your ignition system fires reliably whether you're drifting in an anchorage or running at wide-open throttle.
