I have been researching the correct oil filter for ZR-1s. I own a 90 with 14xxx miles and the JM shows a PF970, black label, no "Duraguard" and was used in 90 to 91. My understanding was that in 92 (maybe 93) the filter went to a PF970C that had "Duraguard" on the label, no barcode. Marc Haibeck's site (zr1specialist) notes that this filter was factory-installed on his 93. I have gotten other information, however, that later model ZR-1s also came with the PF970. Sooooooooooooooooooooo, I don't have all the judging manuals for the Zs and would like an informed answer from the gurus here.

Thanks for the time

Jim
