to clarify .. i have both as we have two xFs ... the stock looks like a better deal for a daily driver that will see rain.
I powerwashed my car while it was running at the do-it-yourself carwash with no problems. couldn't find a drop of water in the CAI.
I was far from gentle with where i sprayed, granted I didn't shove the wand into the grill to blast the filter directly, but my car got a very THOROUGH spray-down that day.
