K&N only way to go, I have the K&N E3050 on both my Model A's

The calculation on the below web site are at an engine running 2800 rpm, and the conclusion is you can use any one of three filters, they conclude any of the three filters below are adequately sized.
◦K&N offers several filters that can be used with the Air Maze housing.
◾Part # E-3050 is 3.5 inches long.
◾Part # E-9257 is 5.5 inches long.
◾Part # E-2040 is 6.625 inches long.
But the site makes this recommendation.
“◦To provide some margin for the filter getting dirty, before you get around to cleaning it, I would recommend the 5.5 inch long length. I know it is an over kill, but I am currently using the 6.625 inch long one to allow for driving on dusty gravel roads and to extend my time between filter cleaning / re-oiling cycles.”
