I think the ulimate solution would be a SRI modified with well constructed heat sheilding as well as fresh air (cool air) ducting from the underside to the filter. It will work near identical to a CAI but as far as servicing the filter, it'll be much easier. Correct, the air comes from beneath (and also around) as displayed in the pic you attached. I would remove the stock box under all the stock box arrangement but also a flex duct/silicone hose or similar to direct air movement via a radius bend straight to the filter.
Check out mine next time if you like. Myself and a couple of other guys have CAI's with K&N high flow filters, on a 14 degree night we're sucking in 15 degree temp air!
