The filters in the picture will not get you full NCRS judging points. They are service replacements. Th original filter is a PF970. No "C" in the number and "Duraguard" is not printed on the lable. The original filter was only installed at the factory and was not for sale to the public. You will see original filters on crate LT5 motors that have never been installed. I have never seen an original filter for sale but you never know. If anyone has any different information on these filters let me know. This is the standard we are currently using when judging 90-91 ZR-1.
