Production technology of MANN+HUMMEL USA
MANN+HUMMEL can produce its whole product portfolio in the USA due to its local production capabilities. Thanks to
the continuous enhancement of production technology, complex products can be realized in the highest quality. Current
main products are air cleaner systems, intake manifolds, and battery trays.

The 1960’s were significant years for the global motor industry and one car launched at that
time, was to gain iconic status – the Ford Mustang. Considered to be the original ‘pony car’ it
continues to be revered and sought after today as it was decades ago. MANN+HUMMEL has
enjoyed a close working relationship with Ford Motor Company over the years. To the joy of the
