Installation Guide

1. Safety First: Ensure the engine is off and cool. Disconnect the negative battery terminal to prevent electrical hazards.
2. Locate Wires: Identify the spark plug wires on your engine, noting how they are routed from the distributor/coil pack to each cylinder's spark plug.
3. Replace One-by-One: To avoid mixing up the firing order, remove and replace only one wire at a time. Gently twist and pull the boot off the spark plug and then from the coil.
4. Install New Wire: Match the new 9-inch wire to the one you just removed. Apply a small amount of dielectric grease to the inside of each boot for easier installation and a better seal.
5. Secure Connections: Firmly press the new wire boot onto the spark plug until you feel it click into place. Attach the other end to the corresponding terminal on the distributor or coil pack.
6. Repeat: Continue this process for the remaining wires, ensuring each is properly seated and routed correctly to avoid contact with hot or moving parts.

Troubleshooting & FAQ

Q: How do I know if these wires will fit my specific engine model?

A: These 9-inch wires are designed for various Johnson/Evinrude V4 crossflow engines (80-140 HP) from the 1980s and 1990s. Please consult the 'Compatible Engine Models' table and cross-reference your OEM part number (e.g., 582365, 582134) to ensure a perfect match.

Q: What are the signs that my spark plug wires need replacement?

A: Common symptoms include engine misfires, rough idling, difficulty starting, reduced fuel efficiency, or visible damage like cracking, burning, or corrosion on the wires and boots.

Q: How do these silicone wires differ from standard ones?

A: These wires feature a silicone housing with stainless steel conductors. This provides excellent resistance to heat, corrosion, and moisture, while preventing voltage leaks (arcing) for a more reliable and powerful spark.
