Replacing Engine Spark Plugs

Model: Mazda 6 MK 1, GG - Years 2002-2008
Part: Spark plugs

Gently remove the plastic cover protecting the engine by lifting it upwards. For safety, disconnect the negative terminal of the battery. To avoid mixing up the cables, disconnect only the first spark plug. Using a 10 mm socket, undo the retaining nut of the first spark plug and pull the connector upwards. The first spark plug is located at the bottom of the well. Before proceeding with the removal, thoroughly clean the wells with compressed air to eliminate any dirt that could fall into the combustion chamber. Using the appropriate spark plug tool, which has a rubber grip, carefully insert it onto the spark plug head and unscrew it. Proceed with caution to avoid dropping foreign objects into the well. Replace the spark plug with one of the same model, carefully inserting it into the well, always using the appropriate tool and turning it gently, ensuring it screws in properly without forcing.
