The spark plugs should be changed at the
intervals specified in the vehicle maintenance
schedule in section 5, or whenever engine
performance indicates they should be changed.
Symptoms that suggest poor spark plug perfor-
mance include engine misfiring under load, loss
of fuel economy, poor acceleration, etc. When
spark plugs are replaced, always use spark
plugs recommended by Hyundai. The use of
other spark plugs can result in loss of perfor-
mance, radio interference or engine damage.

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 center cover on the engine
rocker cover (DOHC Only).
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.
3. To remove the spark plug cable, pull straight
up on the insulated connector, not the cable.
Pulling on the cable may damage the carbon
core conductor.
