My car came with filters but I prefer the look of open stacks in this case. I currently have temporary screens in the foot of the stacks. I am thinking of replacing those with less restrictive, coarser permanent screens that will at least catch nuts, bolts, washers, gravel, etc. And then purchase or fabricate a set of snap on filters that will likely be somewhat restrictive. That way I can run open or filtered stacks depending on the outing.
Below are photos of the filters that came on the car. I still have this setup in a cabinet. They are quite nice. The prior owner had them ceramic coated when the engine was being rebuilt. He then ran out of money and I picked up the project.
