I have received quite a few inquiries as to what a factory installed filter looks like. All of the people have been preparing for NCRS judging.

This is an oil filter that was installed by the factory on an engine that I verified as a genuine 1991 crate engine.

I also found this same filter as the original filter on a '92 car.

A picture of a 1993 factory installed filter is in the 2006 oil filter article.
