There a lot of aftermarket part  from Denso to Bosch and Delphi. You can use a Denso part # 2344317, or Bosch # 15190. Any auto part store should carry a variety of 02 sensor. The range will be from $25 to $50. The myth of aftermarket part is that it does not last long. Well there the side side of that story, Sometimes aftermarket parts exceed the OEM
