Beck/Arnley supplies parts from companies that make parts for OE. So you may buy a Beck/Arnley reboxed part, maybe though the dealer it would be a Denso brand, but because Beck/Arnley is a reboxer of parts, the part you get could end up being Bosch brand because Bosch is an OE supplier or parts. Not that there is anything wrong with that, however, if you want to be sure it is the same part as from the factory from the same company, either buy from the dealer, or find out who make the OE part in the first place and buy that brand.
