Coil Wire - Red 36in HEI/Socket

The Coil Wire – Red 36in HEI/Socket by QUICKCAR RACING PRODUCTS is a precision ignition cable engineered for high-performance marine and racing engines that demand reliable spark delivery under demanding conditions. Built for boaters and engine builders who refuse to compromise on ignition integrity, this 36-inch spiral core coil wire connects your HEI distributor or compatible socket-style ignition system to the spark coil with consistent electrical conductivity. Whether you're running a rebuilt marine engine, a high-horsepower outboard conversion, or a custom inboard setup, a quality ignition cable is fundamental to cold starts, smooth idle, and peak performance across the RPM range.

This coil wire features an 11.5 mm spiral core construction wrapped in a durable red sleeved jacket, which provides both electromagnetic shielding and abrasion resistance in the harsh marine environment where salt spray, moisture, and vibration attack unprotected wiring. The spiral core design reduces radio frequency interference (RFI) and capacitive losses, ensuring a clean signal path from coil to distributor—critical for engines sensitive to ignition noise or those paired with onboard electronics like GPS and VHF radios. The HEI/socket-style terminal connectors mate securely to standard HEI distributor caps and coil terminals, eliminating the weak connections that cause misfires and hard starts.

This 36-inch cable is ideal for mid-range engine bay layouts where the coil is positioned forward or to the side of the distributor, making it a popular choice for marine restorations, fuel-injected conversions, and small-block V8 swaps. Installation is straightforward—push the terminals firmly onto the coil and distributor until they seat with a click, then secure the sleeved jacket away from hot exhaust manifolds and moving pulleys using existing clamps or tie-downs. Weighing just 0.49 lbs and compact enough to route through tight spaces, this wire pair works with most Chevrolet, Ford, and generic aftermarket HEI systems; verify your distributor cap terminal configuration before ordering to ensure proper fit.
