NHTSA Complaint #11658821 — 2016 FORD TRANSIT

I was driving for approximately 6 hours in the rain. When I returned to my home location and filled my vehicle,I only got 14 mpg. Nirmally 17-19mpg. So I figured its been a while since Ive changed thecair filter. So I proceeded to change the air filter. It was completeky saturated with water.I am surprised I made it back through the mountanious area w no cell phone connectivety w passengers. I research what I believe is the oroblem The air intake is located directly behind the front grill next to passenger side headlamp. It has a plastic tube (as a air tunnel) that goes into the botton of the air intake bosmx, in which the filter is on to, letting aur to get through to the engine. From the firce of driving, raining and the engine sucking in air. It almost cacumed the rain into as well. The air intake needs to be revised. Befire a engine stall occurs and loss power and control.
