●
Low ambient temperatures
The cold type spark plug is suitable when spark plug knock occurs with the standard type spark plug under
conditions such as:
●
Extended highway driving
●
Frequent high engine revolution
Spark plug (Platinum-tipped type):
CAUTION:
●
Do not drop or shock spark plug.
●
Do not use a wire brush for cleaning.
