Coil Wire Set

The MOROSO Coil Wire Set (MOR72855) is a professional-grade spark plug wire repair kit engineered for ignition system restoration on HEI and socket-style distributor caps. Built for enthusiasts and technicians who demand reliable engine starting and smooth idle performance, this 36-inch cut-to-fit coil wire addresses the critical link between your ignition coil and distributor—a component that directly affects combustion efficiency and cold-start reliability. When spark plug wires degrade, engine performance suffers; the Coil Wire Set restores that vital connection.

Constructed with solid core wire and an 8 mm diameter, this coil wire delivers consistent spark delivery without the electromagnetic interference that can plague suppressed alternatives. The unsleeved design allows for precise routing in tight engine bays while the blue color coding provides quick visual identification during installation or future diagnostics. HEI and socket-style terminals ensure immediate compatibility with most domestic muscle cars, hot rods, and classic engines that rely on these connector types. The 36-inch length provides flexibility for custom routing, with cut-to-fit capability letting you trim to exact engine-bay specifications.

This coil wire set is ideal for engine builders, restoration shops, and hands-on owners performing ignition system upgrades or repairs on vintage and high-performance applications. Whether you're diagnosing a no-start condition or rebuilding an ignition harness from scratch, the solid core construction and standardized terminal design simplify installation while maximizing spark voltage transfer. Weighing just 0.47 pounds and measuring 7.05 x 1.3 x 9.25 inches when packaged, this kit ships efficiently and integrates seamlessly into complete ignition overhauls. Always verify terminal compatibility with your specific HEI cap or coil pack before final installation.
