Airbox or separate Filters? An age old question.

Despite not having one on my bike, I believe an airbox is generally better and bigger (airbox) better still. If I could devise a suitable airbox for mine, I would.

I don't have one because the split single carbs don't easily lend themselves to one (it would need to be very large and an odd shape) but during dyno testing, removing the filters over the stacks freed up 4 or 5 extra hp, presumably because the filter disrupts flow around the intake that an airbox wouldn't.
