Click on this link and read it. There is a link in there for a place that sells them. You could also try a google search.

I found mine on Amazon for about $46 each. However, as long as the front two are plugged in and functioning properly, NO NEGATIVE impact will occure regarding your air/fuel metering or fuel economy. Only the fronts are used for fuel monitoring.

The secondaries are only used for ensuring the cat converters are working. If left either unplugged or disconnected, you will only get 4 codes - two for the sensors and two for the heater circuits. No biggie.

Another option is to have two O2 sensor bungs welded in and purchase two antifoulers and then reconnect your secondaries. This is probably the cheapest route and will resolve any check engine light without concern of the sims failing.
