Installation & Maintenance Guidelines

1. Preparation: Ensure the engine is cool and disconnect the battery to prevent accidental spark during installation.
2. Removal of Old Coil: Unscrew the existing ignition coil using a suitable socket. Carefully detach any wiring harnesses, noting their orientation for reassembly.
3. Mounting New Coil: Align the M4 threaded interface with the engine block or distributor housing. Tighten securely to manufacturer torque specifications (typically 10–12 Nm).
4. Wiring Connections: Reconnect the high‑voltage lead to the spark plug and the low‑voltage lead to the ignition control module, ensuring proper polarity.
5. Testing: After reassembly, reconnect the battery and start the engine. Verify smooth operation, absence of misfires, and correct idle behavior.

Routine inspection should include checking for visible cracks in the ceramic insulator or corrosion on the housing. Replace immediately if any damage is observed to maintain optimal performance.
