Jimm 7/23/2012The air filter box is located ahead on the engine just behind the radiator. You just unhood 3 or 4 clips from the sides of air filter box located under the hood near driver headlight assembly. Then you pull the plastic piece high enough to take the old air filter out. Wipe out the air filter box using a clean, damp rag.
Then place the new filter in its place, push down plastic cover and close the clips.
