The filter element should not be cleaned
and reused. Replace it according to the
maintenance intervals. See “INFINITI Ser-

engine backfires, you could be burned.
Do not drive with the air cleaner
removed, and be careful when working
on the engine with the air cleaner
removed.
. 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.
