Changing the Spark Plugs
You will find it easier to change spark plugs if the
engine is cold. Always change one spark plug
at a time. This helps avoid getting the wires
mixed up.
1. Remove the engine cover.
NOTE:
It is recommended that the spark plugs for
3.3L engines be changed by an authorized
Hyundai dealer.
2. Using a clean cloth, remove any dirt that has
accumulated around the base of the spark
plug so it cannot fall into the cylinder when the
spark plug is removed.
