WARNING
Be sure the engine and ignition switch
are off and that the parking brake is
engaged securely.
CAUTION
Be sure to use the correct socket to
remove the spark plugs. An incorrect
socket can damage the spark plugs.
REPLACING SPARK PLUGS
Platinum-tipped spark plugs
It is not necessary to replace platinum-
tipped spark plugs as frequently as conven-
tional type spark plugs because they last
much longer. Follow the maintenance
schedule, but do not reuse the spark plugs
by cleaning or regapping.
cAlways replace spark plugs with rec-
ommended or equivalent ones.1. On the 1.8L engine, disconnect the igni-
tion coil connectors. Remove the ignition
coil bolts.
2. Disconnect the spark plug cables from
the spark plugs.
When disconnecting, always hold the
boots, not the cables. Mark all cables to
identify their original locations.
3. Remove the spark plugs with a spark
plug socket.
The plug socket has a rubber seal that
holds the spark plug so it does not fall
when it is pulled out. Make sure each
spark plug is snugly fitted into the spark
plug socket.
4. Fit the new plugs, one at a time, into the
spark plug socket and install them.Use
only the specified spark plugs.Turn
each plug several full turns by hand, then
tighten with the spark plug socket to the
correct torque. Do not overtighten.
Spark plug tightening torque:
14 to 22 ft-lb (20 to 29 Nzm)

tension cable to its proper spark plug by
pushing it on until you feel a snap.
6. On the 1.8L engine, install the ignition
coil bolt.
Ignition coil bolt tightening torque:
33 to 44 in-lb (3.8 - 5.0 Nzm)
Connect the ignition coil connector.
The air cleaner filter should not be cleaned
and reused. Replace it according to the
maintenance intervals shown in the
``NISSAN Service and Maintenance Guide''.
When replacing the filter, wipe the inside of
the air cleaner housing and the cover with a
damp cloth.
WARNING
cOperating the engine with the air
cleaner removed can cause you or
others to be burned. The air cleaner
not only cleans the air, it stops theflame if the engine backfires. If it
isn't there, and the 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.
cNever pour fuel into the throttle body
or attempt to start the engine with
the air cleaner removed. Doing so
could result in serious injury.
CABIN AIR FILTER (if so
equipped)
The cabin air filter restricts the entry of
airborne dust and pollen particles and re-
duces some objectionable outside odors.
The filter is located behind the glove box.
Refer to the ``NISSAN Service and Mainte-
nance Guide'' for change intervals.
