REPLACING SPARK PLUGS
If replacement is required, see an INFINITI re-
tailer for servicing.
Iridium-tipped spark plugs
It is not necessary to replace the iridium-tipped
spark plugs as frequently as the conventional
type spark plugs since they will last much
longer. Follow the maintenance schedule in
“INFINITI Service and Maintenance Guide”, but
do not reuse them by cleaning or regapping.
Always replace spark plugs with recommended
or equivalent ones.Remove the retainers
1as illustrated and pull
out the filter element
2.
The filter element should not be cleaned and
reused. Replace it according to the mainte-
nance intervals. See “INFINITI Service and Main-
tenance Guide” for maintenance intervals.
