Installation Notes

1. Disconnect the battery before beginning work to prevent electrical shock.
2. Label each original spark plug wire with its corresponding cylinder number.
3. Carefully disconnect one old wire at a time from both the spark plug and the distributor cap or coil pack.
4. Visually compare the new wire with the old one to ensure the length and boot angles match.
5. Apply a small amount of dielectric grease to the inside of each boot to seal against moisture and ease future removal.
6. Install the new wire, ensuring it clicks securely into place on both ends.
7. Repeat the process for all remaining wires, working one at a time to avoid mix-ups.
8. Once all wires are replaced, route them neatly and secure them away from hot or moving parts.
9. Reconnect the battery and start the engine to test for smooth operation.
