Hmmmm, My Offy intake came from Summit packed in the original box from the factory. They used balled up pieces from the "Los Angeles Times" to fill up the "pockets" around the intake, so I doubt they are manufacturing in Mexico, unless they go through the expense of sending old LA Times to a Mexican plant. The inspection tag from the factory quality control reads "Date of man. April 2005". Also, I had no issues with ports lining up correctly.
