"It is an AC DELCO replacement air filter, not an original one. This filter has a date code of June 1996. If judged it would fall under the standard deduction.
They have to say ACSPARKPLUG and the appropriate part number of A1097C and the color is different that the later AC Rochester air filters and in 1994 a date code started to appear that was not present in the early air filters."
