Drive in the rain lately?? Even though Ford changed the air filter housing from the previous design that did suck in water, I have found that on my 2015 it still gets the filter wet. Get one of these filters.

Another thing to check is the fuel filter. @ 35,000 miles it could be starting to get clogged, or the throttle position switch could be going bad, or the map sensor starting to act up, or the crankshaft position sensor could be out of position, or ......

In other words a lot of things could cause your problem, you need professional help with the correct diagnostic tools to determine the problem. A 2017 should still be under warranty it's time to see your local friendly FORD Heavy Truck Dealer.

Acceleration problem

I had same problem with our 2016 Challenger. Dealership could not determine problem. I did the 5 star tuning upgrade and that solved my problem. I will order the filter mentioned in the previous post, just to be sure. Good luck.

If you add the AFE air filter, pull the air box out and get rid of the baffle inside the lower box. We're not using the entire capacity of the air filter nor are we getting all the air the V10 wants.

This is the picture of my stock air filter. Notice one end is cleaner than the rest? that is the part in the baffled area that has no air flow.



This is the baffle inside the airbox

When we bought our 2012 bounder classic out only had 5300 miles on it. The first thing I noticed was the exhaust pipe was black at the end, running too rich. Could Have been short trips also when it shifted out of overdrive it backfired. I am a huge believer Lucas products so I used it in 3 fill ups. The pipe is now rusty looking and there is no backfire. I also use there oil stabilizer ( pure synthetic) and tranny treatment. You will like the results.

I'll have to take a look at the baffle. Maybe the baffle is there to prevent water infiltration??? Just a thought!!!!

I'm VERY familiar with the water issue. We had it on the 1999. Blinding rain storm heading to FL with all the family and water, water, water being sucked into the front facing air intake. Smart idea for RAM-AIR but a bad idea for RAM-WATER. It did work for both but!!!!!!

On the front of the air box (the side facing out) there is a port, usually covered with a blue cap. That is the feed for the baffled part of the air box. I added a fitting and pipe to that port and made another air source for the air box. The pipe I added goes to the drivers side above the headlight. Very little chance of water getting in. The air box also already has water drains in the bottom of the box.

With the higher flowing air filter in there and the added air intake I find that the RV drives better. Even on cruise control hills are no longer a challenge for it. There are less 5K RPM downshifts too. The V10 needs air, give it all you can.

Crankshaft,

I checked on the front of the AF housing and did not see any access to the baffle side of the air filter. There's no blue cap or any opening on the front except the water drains on the bottom. Also I don't believe there's a baffle on the inside as you showed. Maybe they took the baffle out and that's why there's no access on the outside.

We have a 2013 chassis and yours is a 2014. Kind of strange that they'd make a different set up with the years being so close. I'll post a pic maybe today.

thanks for all of the info, will check the air intake box, but RV is now at dealership as the have to have the windshield resealed due water coming in to and on top of dash, a trough at bottom of windshield and gets about a half inch water when raining.
also l had replaced the original gas cap for a locking cap and am wondering if that might cause the problem, I blew out the vent hole and this past weekend it has not hesitated. if it starts again will take it to Ford and complain to them,,,don't want to do any mods prior warranty expiring.

Now that has me baffled. I don't know why they would change air boxes in one year. When I was searching for information on the air box I found that, at least on mine, there were dozens of Ford vehicles that used the same air box. That's how I found the high flow air filter, I used a different vehicle to find a filter. It was a 2005 Ford F350 with the V10 engine. Please post a picture of your air box, they must have eliminated the blue cap because they crack and let water in.
