Do not clean the spark plugs. If an
electrode is contaminated with
or accumulated objects or dirt, replace the

Use only a ''wire-type feeler gauge'' to
check the spark plug gap if necessary.
To prevent damaging the iridium

use a ''leaf-type feeler gauge.''
Do not adjust the spark plug gap. If the
gap is out of specification, replace the
