US Air Filter

I took my air filter apart to see how hard it would be. Be sure to have a 10 mm socket, a T25 torque bit and flat blade screw driver.

1) Loosen the steel clamp on the output side of the filter housing using the screw driver. Jpg #1

2) Disconnect the connect from the air mass flow meter. JPG 2

3) Disconnect the filter housing from the suction hood intake duct. JPG 3

4) Remove the filter housing from the engine compartment using a 10mm socket two places. Be careful of the air mass flow meter as it is very expensive. JPG 4

5) Remove the screws using the T25 torque bit. JPG 5.

6) Remove air filter and install new filter.

7) Reassemble the air filter housing.

8) Reinstall in engine compartment.
