Is there any advantage to purchasing an oxygen sensor from a dealer or are the after market parts often the same quality?

...In many...many cases the O2 sensors are made by Standard Ignition or Jiffy/ Sorrenson.(same company) They make the majority of the AC Delco (Mr. Goodwrench) parts as well as the FOMOCO/Autolite and MOPAR parts. So to answer your question, No. Providing that the Deaker has released the part from "restricted" to public, your local partstore should supply you nicely with a OEM or better part.
