SPARK PLUGClean, intact spark plugs are determinant
with regard to engine efficiency and for re-
ducing the emission of pollutants.Spark plugs should be re-
placed at the intervals
specified in the Scheduled
Maintenance Programme. Only use
spark plugs of the specified type: if
the thermal capacity is inadequate
or if the envisaged life is not guar-
anteed inconveniences may ensue.BRAKESService brakes:
– front
– rearParking brake
If examined by an expert eye, the ap-
pearance of a spark plug is a sound clue
for locating a fault, even if not involving the
ignition system. Therefore if you are expe-
riencing any engine problems, it is impor-
tant to have the spark plugs checked by Al-
fa Romeo Authorized Services.
