Coil Wire - Blk 36in HEI/HEI

The Coil Wire - Blk 36in HEI/HEI from QUICKCAR RACING PRODUCTS is a critical ignition component designed for high-performance marine and automotive engines that demand reliable spark delivery under demanding conditions. Built for anglers and boaters who run powerful outboards, jet drives, or inboard racing engines, this coil wire connects your ignition system to the distributor cap, ensuring consistent firing across all cylinders during extended runs on the water. Whether you're running a competitive offshore rig or a high-horsepower pleasure craft, maintaining proper ignition integrity directly impacts throttle response, fuel efficiency, and engine reliability when you're far from the dock.

This 36-inch HEI-to-HEI configuration is engineered for modern high-energy ignition systems, featuring a durable black polymer jacket that resists moisture, salt spray, oil, and UV exposure—essential in marine environments where corrosion and degradation happen fast. The dual HEI termination allows direct connection between HEI distributor caps without adapters, reducing connection points that introduce resistance and potential failure. QUICKCAR's construction uses quality insulation and shielded paths to minimize radio frequency interference, keeping your marine electronics and communications gear running clean even at full throttle.

This coil wire is ideal for anyone replacing worn ignition harnesses on HEI-equipped marine engines, whether during seasonal maintenance or emergency troubleshooting on the water. The 36-inch length provides flexibility for engine bay routing without excess slack, and the weatherproof construction means you won't face premature failure from the salt air and spray inherent to boating. Installation is straightforward—simply disconnect the old wire and seat the new HEI connectors firmly on both the distributor cap and coil pack until you feel them click into place. For serious boaters and racing enthusiasts, keeping a spare on board ensures you're never stranded by ignition issues miles from home port.
