How to replace the spark plugs on the Peugeot 108

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

Today we will explain how to independently replace the spark plugs of the Peugeot 108 petrol engine. To replace the spark plugs, open the front hood and lift the four clips that hold the engine cover in place to remove it. Access the three ignition coils that need to be removed to access the spark plugs; disconnect the spark plug power by pulling the connector lever. Using a socket wrench with a 10mm insert, unscrew the nut located on the coil and gently remove the coil. Use a socket wrench with an extension and a 14mm insert to unlock the spark plug.
