I'll do my best to describe it.. First if you don't have the filter they should actually stock it at your local Honda dealer. It is the same one they use in the CRV. The glove box has to come out, then there is a plastic bar you have to cut off and then there is a bar across the front of it you have to unbolt. The bar is the worst part, getting it back in specifically, I pulled half of the dash piece in front of the radio off in order to get my fingers up in there to get the bolts to go in to the threads again. Once the bar is out of the way the cover for the filter just pops out. You might want to put a towel down as you'll find some dirt is just going to fall out of the thing.
