SPARK PLUGS

The cleanness and soundness of the
spark plugs (fig. 19) are very impor-
tant for keeping the engine efficient
and polluting emissions down.
The appearance of the spark plug, if
examined by an expert eyes, is a good
way of pinpointing a problem even if
it has nothing to do with the ignition
system. Therefore, if the engine has
problems, it is important to have the
spark plugs checked at a Lancia
Dealership.

The spark plugs must be
changed at the times spec-
ified in the Service Sched-
ule. Only use the type of plugs in-
dicated. If the heat ratio is less
than required or the life specified
is not guaranteed, problems can
arise.
