Open the hood
Turn off your vehicle’s ignition, set the parking brake, pull the hood release handle and open the hood.
Visualise
You should now be able to see where the spark plugs are located.
Access the coil
Using a ratchet, an extender, and a 10 mm socket, unscrew the 2 bolts and 2 nuts that hold the plastic cover in place.
Then remove the cover.
Remove the coil
Disconnect the power from the ignition coil. To do this, push on the tab and pull on the connector.
Using a ratchet and a long 10 mm socket, remove the bolt holding the coil.
You can now carefully remove the coil, making small lateral back and forward movements.
Clean
Tip: we recommend using a thin plastic tube taped to the end of a vacuum to properly clean around the spark plug. This prevents the dirt from falling into the motor.
Remove the spark plugs
Using a socket wrench, an extender and a 16mm spark plug socket, loosen the spark plug. Finish unscrewing by hand.
Remove the spark plug.
Install the new spark plugs
Grab the new spark plug.
Put the new spark plug in place by inserting it directly into the spark plug socket, which will allow you to gently bring it to the screwing support.
Always start screwing by hand, then finish by fixing it in place with a socket wrench.
Tightening tips
There are several techniques for tightening spark plugs.
You can use a torque wrench and employ the tightening torque recommended by the manufacturer.
Or you can use an angular torque gauge to respect the recommended angle.
Install the coil
Put the coil back, pushing it in as far as possible.
You can then screw the bolt back in using a ratchet.
Reconnect the ignition coil.
Finish the operation
You can now repeat the process on the other spark plugs.
Finalise the reassembly
Put the plastic cover back on.
And screw it back on.
Operation complete.
