Does anyone have information on how to change the cabin air filter? Any suggestions on where to buy the filter for a DIY installation?

 

I can't help with how to do it, but you can probably buy it from acuraparts247.com

Somebody here with the service manual might be able to tell you how to do the change.

 

If it's the one that I think it is (behind the glove box) then it's easy. I saw it (again if it's the same one) when I was installing my ipod musiclink. It's basically a few screws and a tug to get the glove box out and it sits right behind there in a little box with a couple of tabs holding it in. It can be done in a matter of minutes with a phillips screw driver or a ratchet/socket. You should be able to use the first steps of the musiclink installation instructions to get you where you need to be. I think they are posted in the audio section somewhere.
