Repair step
- Start by removing the center nose panel which is located between the head lights.
- Using the 10mm socket, remove the 4 bolts. Don't lose them!
- While lifting up slightly on the panel, pull/push it towards the engine.
- The panel should "pop" out of place. Once removed, place it out of the way.
Repair step
- Next, locate the connector for the mass airflow sensor.
- Before disconnecting the sensor, you must first pop the metal clip holding the connector in place.
- Using a pointy object (a nail or screw will work fine), push the edge of the metal wire clip away from the center of the connector.
- Now you may remove the connector.
Repair step
- Locate and remove the three screws holding the air box cover on.
- Use a phillips head screwdriver to remove these screws.
- Loosen the bolt that clamps the air hose to the air box. Loosen the bolt until the clamp slides freely along the hose.
- Use a phillips head screwdriver for this bolt as well.
Repair step
- Locate the 4 clips holding down the air box cover. There are 2 on each side.
- Using a flat head screwdriver, pop the clips up.
- Once the clips have been popped up, flip the clips up so that they lie on top of the air box cover.
Repair step
- It is time to remove the air box cover. Slide a flat head screwdriver in between the air hose and where it attaches to the the air box cover.
- Use the flat head screwdriver to push off the air hose while you move the air box cover out and down.
- The air box cover is now ready to be removed.
- Wiggle the air box cover around while lifting up on it until it is completely removed.
Repair step
- The air filters are now able to be removed. Simply pull them out from where they sit.
- Once the air filters are removed, blow them out with compressed air.
- If you do not have access to compressed air, you can tap a lot of the dust out of the air filter just by tapping the air filter on your palm.
