There is an after market filter but the brand is not readable. It is black and to the right front on the driver side. It is wedged between the fender and the plastic V-8 engine cover. It is large enogh to include a hole for the washer filler and cap. I am sorry I do not have a photo but it looks simular to the K&n filtrs that appear to be in a box without a top, or cover. anyone know hat it might be?

 

post a picture if you can
