• Before removal, installation or disassembly, be sure to clarify the failure. Avoid unnecessary removal, installation, disassembly and replacement.
• Vehicle components are extremely hot after driving.

  Be wary of receiving burns from heated parts.

• Be sure to tighten fasteners including bolts and nuts to the specified torque.
• Place shop jacks or rigid racks at the specified points.
• Before disconnecting connectors of sensors or units, be sure to disconnect the ground cable from the battery.

Air Cleaner Element

A: REMOVAL

1) Disconnect the ground cable from battery.

2) Disconnect the power steering oil pressure hose (suction hose) from the clip on the side of air cleaner case (rear).

3) Disconnect the connector (A) from the mass air flow and intake air temperature sensor, and remove the clip (B).

4) Loosen the clamp (A) which connects the air cleaner case (rear) and air intake boot assembly, and then remove the clip (B) from the air cleaner case (front).

5) Pull the air cleaner case (rear) backward of the vehicle, and remove the air cleaner element.

B: INSTALLATION

Install in the reverse order of removal.

CAUTION: Be sure to use SUBARU genuine air cleaner element depending on the engine type when replacing the air cleaner elements. Using other air cleaner element may affect the engine performance.

NOTE:

• Check that there are no foreign objects in the air cleaner case.
• When installing the air cleaner case (rear), align the protrusion of the air cleaner case (rear) to the hole on the air cleaner case (front) to install.

Tightening torque: 3 N*m (0.3 kgf-m, 2.2 ft-lb)

C: INSPECTION

1) Check that the air cleaner element has no deformation, cracks or other damages.

2) Check the air cleaner element for excessive dirt.

4) Disconnect the connector (A) from the mass air flow and intake air temperature sensor, and remove the clip (B).

5) Loosen the clamp (A) which connects the air cleaner case (rear) and air intake boot assembly, and then remove the clip (B) from the air cleaner case (front).

6) Remove the air cleaner case (rear) and air cleaner element.

7) Remove bolts (A) and nuts (B) which secure the air cleaner case (front) to the body, and remove the air cleaner case (front).

B: INSTALLATION

1) Install the bolt (A) and nut (B) which secure the air cleaner case (front) to the body.

Tightening torque:
Bolt (A)
6 N*m (0.6 kgf-m, 4.4 ft-lb)
Nut (B)
7.5 N*m (0.8 kgf-m, 5.5 ft-lb)

2) Install the air cleaner case (rear) and air cleaner element.

NOTE: When installing the air cleaner case (rear), align the protrusion of the air cleaner case (rear) to the hole on the air cleaner case (front) to install.

3) Attach the clip (B) to the air cleaner case (front), and tighten the clamp (A) connecting the air cleaner case (rear) and air intake boot assembly.

Tightening torque:
Clamp (A)
3 N*m (0.3 kgf-m, 2.2 ft-lb)

4) Connect the connector (A) to the mass air flow and intake air temperature sensor and secure the harness with clip (B).

5) Connect the power steering oil pressure hose (suction hose) to the clip on the side of air cleaner case (rear).

6) Install the air intake duct. <Ref. to IN(H4SO)-9, INSTALLATION, Air Intake Duct.>

7) Connect the battery ground terminal.

C: INSPECTION

1) Check that the air cleaner case has no deformation, cracks or other damages.

2) Check that the air intake boot has no cracks, damage or loose part.

Air Intake Boot

A: REMOVAL

1) Remove the cover (A) and clip (B) from air intake boot assembly.

2) Loosen the clamp (A) which connects the air intake boot assembly and air cleaner case.

3) Loosen the clamp (B) which connects the air intake boot assembly and throttle body.

4) Disconnect the blow-by hose and remove the air intake boot assembly.
