1. Loosen the clamp that secures the air inlet tube to the engine airfilter cover and disconnect the tube from the cover (for V6 only).
2. Release the clamps that secure the air filter housing cover.
3. Carefully separate the two halves of the air filter housing.
4. Remove the air filter element from the air filter housing.
5. Wipe the air filter housing and cover clean to remove any dirt or debris and to ensure good sealing.

and allow unfiltered air to enter
the engine if not properly
seated.

8. Replace the air inlet tube and secure the clamp.
Note: Failure to use the correct air filter element may result in severe
