spark plugs as frequently as conventional type
spark plugs because they last much longer. Fol-
low the maintenance log shown in the “INFINITI
Service and Maintenance Guide”. Do not service
iridium-tipped spark plugs by cleaning or regap-
ping.
● Always replace spark plugs with rec-
ommended or equivalent ones.

Be sure the engine and ignition switch are
off and that the parking brake is engaged

WARNING
● Operating the engine with the air
cleaner filter off can cause you or others

gine backfires, you could be burned.
Never drive with the air cleaner filter off.
Be cautious working on the engine
when the air cleaner is off. ●
Never pour fuel into the throttle body or
attempt to start the engine with the air
cleaner removed. Doing so could result
in serious injury.
To remove the filter from the air cleaner, push the
tabs
Aand pull the cover upward.

be cleaned and reused. Replace the air filter
according to the maintenance log shown in the

the air cleaner housing and the cover with a damp
cloth.
NOTE:
After installing a new air cleaner, make
sure the air cleaner cover is seated in the
housing and latch the clips

IN-CABIN MICROFILTER

change intervals.
If replacement is required, it is recommended that
you visit an INFINITI retailer for this service.
