I've noticed my gas mileage dropping a little bit with just over 10,000 miles and am wondering if the air filter might be dirty. I can't find any information on how often to change the air filter in the HAH. I also couldn't open the box that the air filter is in. How often should the air filter be changed? Is getting into that box a matter of unscrewing all of the screws and lifting up? If so I'm going to need a longer screwdriver as that last one is pretty far down and right under some wrapped cables. It made me go just trying to get to it.

Thanks

On the HCH, the recommended interval is 30k, however I change it at 25k, when it shows a fair amount of dirt build up. At my 10k oil changes, I will take it out and shake out the loose dirt or run a vacuum over it.

Filters are cheap. Cars aren't. Change one frequently and it will keep the other in good shape- you pick

There is a chance the air filter is restricting some flow, but not super-likely at only 10k. Depends on what conditions you drive in. If you pull it you WILL see visible dirt in the folds after 10k; the extent to which is the question. I think the HAH interval is 15k in the manual? Not sure- I don't have it here.

There is a cable bundle over one of the screws, but it moves over easily. You do need a fairly fat driver to bite those screws. Like any other car I've had, its not nearly as easy as it should/could be, but its still no more than 5 minutes hood up to hood down.

I've always gone:
5k for oil/filter
10k air filter/tire rotate
50k fuel filter

Nice, round numbers- no little stickers needed to remind you. But everyone's got their own way.

It's 15K for severe and 30K for normal conditions.
