Video tutorial

Below we will see the instructions that will allow us to dismantle and replace the spark plugs of the Mercedes SLC 300. First, let's open the hood of the car and start disconnecting all the spark plug coils by unscrewing the screws located at the base; then we use a socket wrench with an extension to unscrew all the spark plugs, as shown in the video.

At this point, we install the new spark plugs, of the correct type and with the same thread pitch; we initially screw them in by hand and then tighten them with a torque wrench, finishing with the reconnection of the coils.
