S90: Airbox

The screws holding the covers on were fused solid.  Not only did I have to do the usual re-slotting with the Dremel, but I had to unscrew them all the way out with the impact driver.  They didn't reach a point where they could be turned by hand until they were almost all the way out.

Even after getting the screws out, I found that only one cover would come free.  The other one was rusted tight.  A couple whacks with the rubber mallet only succeeded in putting a dent in the body of the airbox (lesson learned).

But I don't think it's necessary to get both covers off in order to get a new filter in and make it functional.  It's not pretty, but I think it'll do the job for now.
