News to me, maybe it will be to some of you. Ford has a air inlet tube that raises the air intake higher so as to do away with the water ingestion problem on the F-53 chassis with V10... It replaces the original fix many had done and still have a problem. The part number is XC309F843AA reference from TSB 04-24-22, part cost is $15.39. It is easily installed yourself.
