The 8.5MM Wire Cyl Markers are precision spark plug wire identification tags designed for high-performance ignition systems and engine rebuilds. They are ideal for diagnosing complex multi-cylinder firing orders, swapping ignition components, or documenting custom engine harnesses. These markers help eliminate guesswork and prevent costly misfire issues.
Each marker slides directly over spark plug wires, providing permanent, color-coded or numbered identification. The 8.5mm diameter accommodates standard automotive ignition wire jackets without interference, and the durable construction resists heat, oil, and vibration exposure common in engine bays. The design ensures tight fit retention while allowing quick removal and repositioning when needed.
These markers are essential for serious engine builders, mechanics, and enthusiasts working on carbureted, fuel-injected, or modified engines. They are particularly beneficial for anyone running aftermarket distributors or custom ignition harnesses. Pro mechanics utilize these markers to streamline diagnostics and enhance efficiency during engine tuning sessions.
