2. Remove Engine Cover

Use a socket wrench to remove the bolts securing the engine cover.
Gently lift the engine cover off and set it aside.

3. Access Spark Plugs

Locate the ignition coils on top of the engine, typically near the spark plug wells.
Disconnect the electrical connectors from each ignition coil by pressing the release tab and pulling them out.

4. Remove Ignition Coils

Use a socket to remove the bolts securing each ignition coil in place.
Carefully pull each coil out of the spark plug well.

5. Remove Old Spark Plugs

Use a spark plug socket with an extension to remove each spark plug by turning counterclockwise.
Inspect the condition of the old spark plugs for wear or deposits.

6. Install New Spark Plugs

Apply a small amount of anti-seize compound to the threads of the new spark plugs (if recommended).
Insert each new spark plug into the well and tighten by hand.
Use a torque wrench to tighten the spark plugs to the manufacturer’s specifications (usually around 15-20 ft-lbs).

7. Reinstall Ignition Coils

Place each ignition coil back into its respective place and secure it with the bolts removed earlier.
Reconnect the electrical connectors to each ignition coil, ensuring a firm connection.

8. Reinstall Engine Cover

Place the engine cover back on and secure it with the bolts removed in step 2.

9. Reconnect Battery

Reconnect the negative terminal of the battery.
