I am not too sure on how to remove it. I recall the mechanic showed me how to do this, but since they don't charge for labour to replace the air filter (just the cost of the filter itself), I was not too inclined to tinker with my car.
If memory serves, there are 4 screws that secure the air filter box. Open those, and make sure the sensor wires for the hose do not get bothered and then just remove and replace the air filter.
I am sure the handbook mentions how to do this as well.
thanks for the help the manuel DOES NOT show how to do this!!
