I have a Ford 3930, and just picked up a 3910. I noticed the air precleaner bowl/assembly on the 3930 is a decent amount larger and a different design than the one on the 3910. Was this a design improvement that offers better filtering, and would it be worth updating the precleaner on the 3910?
Here's the 3930 precleaner.....
...and the 3910.
