Hello all,

This is for a 1941 Ford Super Deluxe with a single Holley 94. What are the best options for replacing the stock oil bath filter with a paper element filter. This is intended to be a reliable driver and not a show car.

Thanks in advance!
 
Although this is not a '41 oil bath the same method can be applied.
Filter sizes to fit your application can be looked up here-----

A oil bath will have a much higher particle capture rate than a K&N, but you still have the same maintance just more often with the K&N( clean out the dirty oil, add new oil
 
This was my solution to put a 10 inch air cleaner on my flathead. I had a
crusty oil bath air cleaner that was on a 39 engine. I cut the bottom
out of it and then matched it to a new air cleaner ($25 from O'Rileys)
The bottom hole is set up for a 4 barrel. Then tacked the two
together and now you have an air cleaner that will fit perfectly. Fram makes a 2 3/4 inch filter that I used. This will flow plenty of air.

I'm fine with the old original oil bath air cleaner on the 52 merc although it looks like a very small opening for the air to pass through. I've test run it with and without the air cleaner and it might be my imagination but it seemed to have more power without the air cleaner.

That's probably because the filter element is full of crud and choking off the air flow.

What I can see of the steel mesh in the air cleaner looks very clean and non restrictive. I question the setting of that little disk on top of the "towering inferno" Holley carburetor as it seems to take up a lot of space in the air flow. I'd even wonder if it is necessary to have that disk in there at all. In the shop manual they call it the bleeder screen washer but don't say what it's purpose is.
