I have a focus st with the ford racing snorkel. https://performanceparts.ford.com/part/M-9603-FST They install directly behind the grill so I would think a decent amount of water makes it to the airbox. Would it be safe to run this with a paper filter, or will any water ingestion with rain degrade the filter?

It's a Ford part. No danger whatsoever.

Most, if not all, OEM intakes have a small change in direction and a drain for water to be directed away from the filter.
 
My FXT gets air for the intake (as well as the intercooler) from a similar location and I've certainly never noticed my air filter being wet.
I've never looked closely, but I wonder if the resonator just before the airbox includes a water draining function?

Yep , my thought exactly . If it ain't broke , don't fix it .
 
For $308 it better not void your warranty, yikes! $308 for a K&N and a little scoop.
EDIT: You're not even going to use the filter are you? Ata boy, paper all the way but that makes the price even worse!

My dopey 106 hp Scion Ia has a cold air snorkel just like that and it came free of charge 100% stock.
 
The factory front "snorkel" on my GTI has a drain/divereter for water, no doubt Ford has a similar setup.

Paper filter should be no issue.
 
Unless you go dunking it in 3' of water, it should be fine.

Not that I've done that recently in the Jeep...

It's an aftermarket part with no rain diverter since stock it has no chance of seeing any rain. The airbox does have a drain though so that's not an issue. There are signs of water making it to the airbox, so I was just wondering if a paper element can handle a misting without getting damaged or degrading. If not I'll just stick with my AEM filter. I really just need to pull the lid and see how much water makes it in there after driving in a downpour.
