REMOVAL
1. Remove engine cover with power tool. Refer to
EM-19, "Component".
2. Remove ignition coil. Refer to EM-42, "
Component".
3. Remove spark plug with a spark plug wrench (commercial ser- vice tool).
INSPECTION AFTER REMOVAL
Use the standard type spark plug for normal condition.
The hot type spark plug is suitable when fouling occurs with the standard type spark plug under conditions
such as:
 Frequent engine starts
 Low ambient temperatures
The cold type spark plug is suitable when spark knock occurs with the standard type spark plug under condi-
tions such as:
 Extended highway driving
 Frequent high engine revolution
