Side topic, bit of trivia if of any interest, but I once worked at Siemens at their automotive induction and intake manifold division in Tilbury, Ontario, Canada. They told me it used to be a Fram facility way back then. They still had all the original drawings for the six pack / bbl and Hemi air cleaner assemblies, as they designed the assemblies for Chrysler not just the filters. Today it's a Mahle facility, Mahle bought that division from Siemens.

Cheers,
Mike
