To access the spark plugs on the Subaru Forester, you need to remove the components located on the sides of the engine block: specifically, loosen the bolts securing the battery and the air filter housing, disconnecting the connectors attached to the coils.

Once the coils are freed, you can extract them from their housing and remove the spark plugs using a spark plug socket.

This way, you can insert the new spark plugs into their housing, then reassemble all the components that were removed.

Once all tyres have been inflated to the recommended pressure, turn on the ignition to check that the light has disappeared: if it is still present, it may be necessary to drive for a few miles, allowing the sensors to work and thus turning off the light.
