Nearly all the REM foams separate at the seam. There is no lip like the OEM foams, diameter is smaller, and the foam cells are much larger than OEM.
I believe there are no surviving OEM foams today. I had some NOS ones in boxes that crumbled when removed from the box.
I remember seeing a comparison of air flow between foam filters & paper showing paper better than foam in every way except appearance. Anyone else have info on this?
