Suggestion
Maybe just peace of mind...but after many air filter changes I've never noticed any sign of water that has got on the filter.
Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

Never tried but if air can get in so can water.
I've driven in very heavy rain more than once with no problems but there was a time I was worried.
It was after a heavy rain with local flooding. Where was I... Oh Higginsville in MO on 13 highway north of I-70.
Some streets were curb deep in water and I took it slow and there were no problems.
But I paused when I came to a rail road undercrossing that was flooded. I was in traffic and couldn't back up. I could tell from the cars coming through from the other direction the water wasn't too deep but I do not recall how deep now only that was over curb deep but under a foot deep I'm pretty sure. (I've seen this collect several feet of water easy but not this time.)
As I was getting ready to enter the water from the other direction a big rig was coming down into the water and I was worried the tire splash would get water into the intake so I got on the CB radio (hand held unit) and called out to the driver to go slow to not splash my car and he answered back he would go slow and he did.
The Boxster made it through with nary a problem.
Might add that when I checked the air filter in my Turbo it looked like it had gotten a bit wet. I am careful when I *wash* the car and spray water in that area but I don't worry even when the car it out in the rain. I know the engine gets wet because the belt slips upon startup and at least once the engine misfired enough to turn on the CEL.
A little water in the engine is actually good for it. Cleans out the combustion chamber. As long as it doesn't hydrolocks, it will be fine and for that, you need a ton of water.
Live in Florida. Sometimes we get torrential local rain...just enough time to dump 3-4 inches in some places and flood the roads. During an air filter change I had the airbox out and did a little mental calculating. There is one small drain hole in the bottom of the airbox. With the snorkle on the airbox and rising to the bottom of the spoiler, I figured during the locally heavy rain quite a bit of water would get in there. So I flipped over the airbox and made that drain hole larger, then added two more on the bottom along the slope where the water can collect. Maybe just peace of mind...but after many air filter changes I've never noticed any sign of water that has got on the filter.
Check your frunk for water encroachment. When left outside during torrential rains these cars have been known to collect rain water in the brake master cylinder vacuum assist chamber. (I don't remember just how it gets in there) Upon start up the vacuum from the engine sucks the water out of the vacuum chamber and into the engine where it hydro-locks the cylinders.
Sounds like you may have had some of this happening. Hopefully your engine was not harmed.
