The dealership I go to wants $100 to purchase and install the filter! My old X came with the filters but the new one did not. Thought there was cutting to the air box involved as the instructions on that come with the replacement filters indicate to..

“cut out the plastic shaded section indicated by the shaded area above the tab using a utility knife”

So I almost let them do it so I would not risk screwing up the air box. First time I took the glove box off to run some wires behind the dash I discovered my new X’s air box was precut and has a cap over the area that you just pull off and replace with the filters. How cool!
