    The first step for replacing the air cleaner is to take off the engine electrical connector from the maf/iat sensor. Loosen the screws of the air cleaner housing and take off the cover to remove the Air Filter. Place the new Air Filter in and cover the housing with the air cleaner cover. Be sure to tighten the air cleaner housing screws with a torque of 3 n.m (27 lb in) and connect the engine harness electrical connector to the maf/iat sensor.
