and the 208 and other filters for the Z32 correctly do not have a bypass valve. The Z32 engine has a bypass check valves built into the engine oil system and the release pressures are factory set. Filters with a bypass would probably upset the internal bypass balance pre set in the engine design. So in a pinch for the 209 is correct but there are other filters out there that are for the Z32 without bypass valves. The 60U00 probably has no by pass valve does the 55Y have no no bypass valve.
