How to replace the spark plugs of the Mercedes A-Class

Model: Mercedes Classe A W176 - Years 2012-2018
Part: Spark plugs

To replace the candles of the Mercedes Class A, we start by removing the upper engine protection, remove the air tube located above the spark plug wires, unscrewing the clamps; once the air tube is removed, we proceed to remove the bolts holding the spark plug wires, disconnect the connectors of the spark plug wires and remove the wires; once the wires are removed, we proceed to remove the candles with a socket wrench and extensions; once all 4 candles are extracted, we blow on the spark plug wires, position the candles in their seats, screw them in with the correct torque, put back the wires, screw back the bolts of the wires, reconnect the connectors, put back the air tube by screwing the clamps and put back the upper engine protection.
