2. Reposition the locking clip on the
connector (connector shown from
below for clarity), squeeze the
connector and pull it off of the air
outlet tube.
3. Clean the area around the air
tube to air cover connection to
prevent debris from entering the
system and then loosen the bolt on
the air tube clamp so the clamp is
no longer snug to the air tube. It is
not necessary to completely remove
the clamp.
4. Pull the air tube off from the air
cleaner housing.
5. Release the three clamps that
secure the cover to the air filter
housing. Push the air filter cover
toward the center of the vehicle and
