well, $800 is stupid, but $400 not so much. you do a 987 airbox it will cost you $200 or so with txes and shipping, at which point you have to do a bunch of fabrication (time = $) and buy couplers, joiners, elbows, hose clamps, etc. i mean, the gas for the multiple trips to the post office/hardware store adds up, you know?
the water issue is a red herring. one guy on planet 9 installed one and drove it in a torrential rain and saturated the filter. became a big deal, impacted sales, so now vendors are trying to mitigate it. with my 987 air box, and the trimming i have done to the filter hanger, etc., there is a clear shot from my filter to the great outdoors (rain and all) and never had an issue.
otherwise, it is easy to fabricate and there is a how-to on this forum. a piece of lexan cut into a trapezoidal shape, a cone filter, and some silicone/couplers.
my review of it was this: resistance to airflow caused by the air filter is proportional to area; the larger the filter surface area the better (hence why the 987 air box is such an improvement over the 986 unit). measuring the inside of my fender well, there was no way i was going to fit a filter as big as the one in the 987 airbox.
