i broke mine when i was installing my headers, cars runs great even thought it isnt installed, but where can i get on online

 

your probably best to get it at the dealer. with patent laws and stuff, the pep boys type places sometimes have to charge more.

i suggest hunting around, but might as well start at the nearest dealer as base line.


and the car might seem to run fine, but the O2 sensor plays a significant role in your fuel and timing. i wouldn't run around for a long time without one.

 

You might be able to get aftermarket like this one:
