Installation Guidelines

1. Preparation: Warm up the engine to operating temperature before removal to avoid thermal shock.
2. Removal: Use a spark‑plug socket and breaker bar. Rotate counterclockwise until free, then carefully lift out.
3. Inspection: Check for wear or damage on the old plugs; replace if any signs of deterioration are present.
4. Installation: Align the plug with the cylinder head, hand‑tighten to avoid cross‑threading, then torque to the manufacturer’s specification (typically 100–120 in·lbf).
5. Gap Check: Verify the spark gap using a feeler gauge; adjust if necessary to match the vehicle’s specifications.
6. Final Checks: Reconnect the ignition leads, start the engine, and listen for smooth operation. Monitor for any misfires or irregularities.

Maintenance Tips

• Inspect spark plugs every 20,000–30,000 miles or as recommended by your vehicle’s maintenance schedule.
• Avoid using excessive force when tightening; over‑torquing can damage the threads.
• Keep the engine bay clean to prevent debris from contacting the new plugs during operation.
• Store unused spark plugs in a dry, dust‑free environment to preserve their integrity.
