SPARK PLUGS
Replacing the Spark Plugs
Changing the Spark Plugs
The  spark  plugs should  be  changed  at  the
intervals specified in the  vehicle maintenance
schedule in Section 5 or whenever engine per-
formance 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.

NOTE:
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.
Your engine was originally equipped with plati-
num-tipped spark plugs. (For 2.7L only).
Platinum-tipped spark plugs will last longer than
conventional type spark plugs and can be iden-
tified by blue lines on the ceramic shell.
When replacing  the  spark plugs,  genuine
Hyundai   replacement   parts  are   recom-
mended.
