How to change the spark plugs of a Peugeot 108.

Model: Peugeot 108 MK 1 - Years 2014-2021
Part: Spark plugs

Let's see how to change the spark plugs of a Peugeot 108: usually when something is very easy, we see a girl doing it in mechanic videos, as in this case. We open the hood, remove the engine cover, and take out the air filter. This step is not necessary, but it creates space. Above each spark plug, there is an ignition coil with an electrical connector and a cable that goes to the control unit. We disconnect the electrical connector, unscrew the bolt with a socket wrench, and gently pull the coil upward to remove it. We clean the area around the spark plug well to prevent dirt from falling into the combustion chamber; then we insert a 16 mm spark plug socket and loosen the spark plug counterclockwise; we extract it with a magnet and repeat for all three spark plugs, placing all three spark plugs in order for reference. We insert the new spark plug gently using a magnet or a magnetic socket. We hand-tighten it clockwise to avoid cross-threading, then we tighten it with a torque wrench to 25 Nm. We put the coils back in their slots, screw the coil bolts back in, reconnect the electrical connectors, reassemble the air filter and the engine cover. Operation completed.
