Would OEM zealots murder me for fitting a custom foam&fiberglass airbox to a 931?... I mean, stock one is nice and all, but I want to have an ability to go to the store and buy the damn air filter, isntead of ordering it for insane amounts of money... Plus the stock steel one seems awfully heavy and grabs this very hot air right out of the radiator...

I just run a open element cone filter up there, purolator brand, from advanced autoparts...

But how do you deal with those two lines coming into the filter box?... Or do you run the box empty, and put the cone filter on the intake pipe of the filter box?...

Hm, that sounds like a good solution, actually. Where does all the oil go, btw? IIRC one of the tubes spits oil, at least mine had an oily streak on the filter box.

Yeah, one i have open and the other just a cheap filter breather attatched to it. Nothing fancy. Id say you'd be fine by just putting a small breather filter on each line that goes into the box, possibly have to change them once in a while(2$ so not expensive).

I use the stock filter but I cut a rectangular hole in the leading edge and a box welded it to the front and I get air from the front of the car. I have a round filter that I will modify with a tube and have it behind the headlight. I will insulate the tube because it is over the radiator. I will put it on in the spring too cold out now.

Actually the 931 stock air cleaner snorkle grabs cool air that is directed above the radiator.

Well, my solution was to cut a big rectangular hole in the lower half of the stock box, and remove the snorkel, and put a metal plug in where I removed the snorkel. All fo the air now comes in from the nose grills, straight into the box. That, and the addition of a K&N, made a big difference.
