Coil Wire -Blk 18in HEI/HEI

The Coil Wire - Blk 18in HEI/HEI is a precision ignition harness engineered for high-performance racing and street engines running HEI distributors. Built for reliability in demanding conditions, this 18-inch coil wire connects your HEI ignition system to the distributor cap, transmitting critical spark energy with minimal signal loss. Whether you're tuning a classic muscle car, hot rod, or race engine, a quality coil wire is non-negotiable—poor connections or degraded insulation rob horsepower and cause misfires.

This Quickcar Racing Products coil wire features a spiral core design with 11.5 mm diameter and durable black sleeving, both protecting the conductor from heat, vibration, and electromagnetic interference. The HEI-style terminal ensures a secure, low-resistance connection to your coil and distributor, critical for maintaining spark integrity under boost, high RPM, or extreme ambient temperatures. The 18-inch length provides versatile routing options without excess slack that invites noise or contact with hot engine surfaces. At just 0.3 lbs, it integrates seamlessly into lightweight builds without adding unsprung mass.

This coil wire is ideal for engine builders, race teams, and enthusiasts upgrading aging or failed ignition harnesses on HEI-equipped platforms. Installation is straightforward: simply disconnect the old wire, press the HEI terminal firmly onto the coil and distributor posts, and secure the sleeved section away from headers or moving components. Compatibility extends across most domestic V8 and V6 engines modified with HEI systems, making it a go-to replacement or upgrade for carbureted hot rods, fuel-injected race cars, and restoration projects seeking reliable spark delivery and clean engine bay aesthetics.
