Even if used plugs appear to be in good condition, they should be replaced every 10.000
km.
N.B. - Values lower than 0.7 mm can compromise the engine life.
WARNING!
To avoid either malfunctioning or inefficiencies of the ignition system, the spark
plug wire connections (spark plug cap) and the spark plugs must be of the
recommended type (as original equipment). Do not make any plug current check if
the original spark plug cap are not fitted otherwise the electronic power box would
be irreparably damaged. Bear in mind that this also applies to any vehicles
equipped with the electronic ignition systems listed below.
