Mann Oil Filter Decal (early), 356

Oil filter decal. Mann decal-early. 356's & 912's used three types of oil filters. The Mann filter was used for the most part on early 356 (or pre "A") and possibly a few very early A's. This filter is identified by a 10mm bolt. The rest of the cars used either the H-filter (which is identified by a 16mm bolt) or the Fram filter (which is identified by a 12mm bolt). Since there are no chassis or engine number breaks which denote the use of these filters, it is best to measure the bolt to identify your filter. Also, H-filter canisters are generally either all silver or silver with a black cover while Fram canisters are orange with a black cover.
