EMPI, stands for Engineered Motor Parts Incorporated, and the company
was known for
selling aftermarket
speed parts for Volkswagens. The company started in the 1950's, and sort
of ended in
the 1970's. (I say sort of for a reason. You can still buy EMPI labeled
parts today,
but they're a far cry from EMPI of old.)
