o'reilly's has 3 quality levels. the MasterPro 1yr Wrty, the Borg Warner, and the Borg Warner Select. the first two are aluminum, the first is crimped, the second is soldered, and the Select is brass soldered. the first level of BW has a P at the end of the part #. The BW Select has no P at the end of the part number, it'll just be the normal number. That will be the one you want.
