I will not use a Bosch part unless I am working on a German or Swede car. Everytime I have used a Bosch Part on an American or Japanese car, I always have problems with either the operation or performance of the vehicle.
My other option, although many times I may pay more, I use Standard/Blue Streak products. Most of the Carquest brand parts are made by Standard adn they are also sold by Schucks and Checker.
I go to the online catalog from Standard and get the part numbers which I give to the parts store counterperson.
