you can do it yourself if you have a drill with decent drill bits. do not just drill out the stock holes. the wing came with those little black things, there should be 4 of them . stick them in the holes on the bottom of the wing and lay it on your car and put it where it fits by the thin area on the trunk and them tape those things down to the top of the hatch. the little hole in the middle of the black things is where your holes should be . just stick something down the hole and make a mark in each one. This probaly makes not sense but it is hard to explain
Do you have to have Acura do it? I mean a body shop would do it for much cheaper... Where I'm from, most dealers don't even have the equipment or time to do such things, they'd just send it off to a nearby body shop.
