Hey Metlic, yeah I read it wrong, well I had somethings backwards in my head.

So I guess I should replace just the rear o2 sensor with an OEM one, instead of doing both with the cheaper aftermarket.

Going to buy everything tonight, last chance on the o2 sensors. Is there a great place to buy OEM ones online?
