Part: Spark plugs

Replacing the spark plugs will provide many benefits, starting with engine starting, as well as performance and fuel consumption; it is recommended to let the engine cool down and then proceed to remove the plastic cover located right above the engine: the spark plug tubes are immediately visible in front of the oil fill cap; disconnect the power connectors of the tubes, remove them, and blow compressed air into the spark plug holes to eliminate any dirt that could enter the cylinders; then unscrew the old spark plugs and screw in the new ones without exceeding the torque specification, then apply the tubes and reconnect the connectors.
