Check Engine Light
We’ve had a ton of rain in the south east the last few months. I travel about 100 miles round trip on I-40 & I-95, five days a week. I set the adaptative cruise control and often times fall in behind an 18-wheeler. Friday the check engine light illuminates, absolutely zero change in any other indications. Get it to the dealer and the lap top tells the tech air filter (only 5800 miles), he shows me the filter and the pleats look like fried bacon. Seems when I follow the big rigs the fine mist enters the air cleaner snorkel above the passenger headlight and saturates the air filter. The repeated wet/drying events caused it to fail. A new $94 dollar filter and problem resolved.

If you think it might be a recurring problem, you may want to look into getting a marine grade water resistant filter. I used one made by Donaldson on a 7.3 diesel I previously owned.

Thanks for posting that good-to-know information. FYI, air filters (and other Motorcraft maintenance items) are much less expensive at the following link. I order $250-worth to qualify for free shipping.

Correct spelling is fading. Look how many posters here can't punctuate. OTOH, I had an, "Oh, Baby!" moment when the stork delivered my first Ford diesel.

It’s the new world, millennials. If the software doesn’t auto-complete or auto-correct, forget about getting it right...but yes, if you’re in sales, the least you can do is spell it right for the masses.
But, to the OP - I worry about a design like the S&B that moves the air box in front of the battery. It seems like there’s more chance of this happeneing with the inlet and filter closer to the front of the truck. Lots of road-time on my 6.7L 2017 still to come...

IMO that filter should have been replaced under warranty - these are vehicles, theyre not restricted to sunny day driving only.
certainly that filter should last SIGNIFICANTLY longer than 5k miles....either there is a design flaw in the fresh air intake or the gaskets leading to the filter are leaking!

I will not disagree! I was pleased and thankful the dealership got me in on the Friday before Christmas to at least tell me I could take on the 50 mile journey home and not be in limp mode.
Does anyone one know of a mechanism to notify Ford of such an event?

These engines make a lot of power which requires moving a lot of air. Even if you had a snorkel facing to the rear, driving in a cloud of water would still soak the filter.
I spend a lot of time driving in the rain and change the air filter about every third oil change, though I physically check it at every change. One particularly wet month resulted in a very nasty, black filter. Very glad that filter is sacrificing itself to protect the somewhat more expensive engine.

In all fairness they’re not intended for underwater operation, either.

this is a truck....surely its capable of being driven in the RAIN w/out destroying the air filter every 5000 miles!

KInda what I was thinking. What's getting into the intake if these filters are taking on that much water?

If you are changing your air filter every 5000 miles due to water, you're driving a submarine, not a truck.
In 80,000 miles, I've changed my air filter three times. The last two times didn't look nearly as bad as the first time, but I look at it as pretty cheap insurance.
