Product Details
This 9-inch Spark Plug Wire Lead is designed for selected Johnson, Evinrude, and OMC V4–V6 outboard applications. It features a Kevlar core, stainless-steel wound conductor, silicone jacket, and silicone boots for durable ignition service and reliable resistance to heat and moisture.
Use the reference numbers below to compare this lead with the wire currently installed on your engine. Because fitment can vary by engine model, year, ignition configuration, and serial range, confirm the original part number and physical configuration before ordering.
- Replacement Design: Intended to replace a matching factory-terminated spark plug wire without cutting or fabrication.
- Durable Construction: Kevlar core, stainless-steel wound conductor, silicone jacket, and silicone boots are suited to marine engine environments.
- Ignition Service: The conductor and insulation are designed to provide dependable spark delivery and interference suppression when correctly matched to the application.

Engine & Model Compatibility
This lead is intended for selected Johnson, Evinrude, and OMC V4 and V6 outboard applications. The available information does not establish a complete model-year, horsepower, or serial-number range, so do not rely on engine brand or displacement alone.
Before ordering, match your existing wire's part number, overall length, terminal ends, boot shape, routing, and connection points with the information above and the wire being replaced. If any of these details differ, verify the application with a qualified marine technician.

Installation Notes
- Safety First: Disconnect the battery where appropriate and ensure the engine is cool before beginning work.
- Remove the Old Lead: Identify the correct spark plug wire. Grip each boot rather than pulling on the wire, then twist gently while disconnecting it from the spark plug and ignition connection.
- Compare the Leads: Place the replacement beside the original to confirm length, terminal style, boot shape, and routing.
- Apply Dielectric Grease: If appropriate for the application, apply a small amount of dielectric grease inside each boot to help protect the connection from moisture and ease future removal.
- Install the Replacement: Push each boot firmly onto its corresponding terminal until the connection is fully seated. Do not force a mismatched terminal.
- Route and Test: Route the lead away from hot, sharp, or moving components. Reconnect the battery if disconnected and test the engine for proper operation.
Troubleshooting & FAQ
How do I confirm that this is the correct wire?
Match the original wire's part number, length, terminal ends, boot configuration, and routing. Engine brand or horsepower alone is not sufficient because fitment may vary by model, year, ignition system, and serial range.
What are the signs of a failing spark plug wire?
Common symptoms include rough idling, misfires—especially under load—hard starting, reduced performance, and visible cracking, burning, corrosion, or damage to the wire or boots.
Can I cut this wire to a shorter length?
No. This lead has factory-terminated ends and a specified 9-inch length. Cutting it can damage the conductor and prevent a secure electrical connection.
What does RFI suppression do?
Radio-frequency-interference suppression helps reduce electrical noise generated by the ignition system that may affect marine electronics such as radios, GPS units, fish finders, or stereos.
Is this an OEM part?
This listing is for an aftermarket replacement lead. Confirm the reference number and physical configuration against your original component before installation.
Should installation be performed by a professional?
If you are unsure about the ignition connection, engine application, or wire routing, have the work completed or checked by a qualified marine technician.
What are the shipping and return terms?
Shipping availability, delivery estimates, and return eligibility are shown at checkout and are subject to the applicable store policy.
