- we were in a driving rainstorm in texas one afternoon...a real toad strangler. as we were climbing a hill a few miles from our campground we suddenly lost 90% of our power...the MH struggled to climb the hill and for a time I wasn't sure we would make it. I had the pedal to the metal as they say but was hard pressed to make more than about 10-12 MPH on level ground. we made an appt. at a local ford truck service shop for the next day and they found that the standard sir filter was literally soaked with rain water. the mechanic was amazed that any combustion was taking place let alone enough to propel the vehicle forward. the solution was to replace the cardboard AF with an K&N air filter. they can be a bit pricey and they do need periodic service but problem solved.
The K&N may have solved your water ingestion (or maybe not-----depends on the next rain condition). However, it has some other problems including possible oil contamination of your MAF sensor and reduced filtering of the air stream (increased engine wear).
Ford's fix was: http://www.thedieselstop.com/faq/9497faq/tsb/tsb/files/042422.pdf
Do not use a K&N air filter. Get the new intake tube and save the shield. I put the shield at the top of the new intake tube to shield it from rain coming in through the front grill.
