Sorry, I know this is another overkill question, but I want to make sure I am buying the right part. Are these cars particular to an O2 sensor in the same way they are to thermostats? Do I need to buy OEM or can I buy aftermarket? Which aftermarket ones are BEST and which to avoid?

 

Thanks.

My Loyale came with Bosch from the factory. I am on the third Bosch now. No problems what so ever.

Thanks. I finally found a thread that said Bosch was the way to go, but they are really not too picky. I just wanted to be sure before I went and bought one of those parts that could be OEM only.
