This premium oil filter is a "assembly line correct reproduction" of the original filter installed by both assembly plants when your engine was built. Assembly line oil filters were black on white and never had a date code. A huge amount of time in research,examining original filters that still exist and application has been spent to insure correctness and details are exact. The filter is national judging correct. This filter does not have the embossing as some very early AC production filters had. The majority of filters did not have embossing. For your info, the white, red and blue repros sold today are a repro of the over the counter replacement filter that was used by the GM dealerships and parts houses back in the day.The original black and white filters were discontinued and the white with red and blue were predominant in the seventies, If you want your engine 100% correct, this filter is the finishing touch for the purist Camaro enthusiasts.

Thanks for looking!
