the throttle body in the focus/contour are the exact same size/thing though, so it should work, but since ours sits vertically, maybe there would be clearance issues, i don't know. i think the space is about an inch tall, or maybe an inch and a quarter. it runs $90 by the way. i was trying to do some more research, apparently they used to use a similar thing with carbeurated engines. it gets you better gas mileage, and more horsepower apparently by the better atomization of fuel.

I would say it won't cause the throttle body in the focus sites differently that it does in the contour. but you never know unless someone has tried.
