Cheapest place to purchase a stock primary O2 sensor?

[Joey Link]

According to my OBD code my primary O2 sensor is having problems. Where's the cheapest place to buy an OEM replacement? Should I go with OEM or go with a Bosch replacement? A stock part number would help as well.

as always, bmaparts.com, call and ask for patrick, he hooked me up with a new o2 a few months ago, haven't had a problem since

Check for vacuum leaks first.

Bosch is OEM, so yes you can get one of those.

Are there any write-ups on how and where to check for vacuum leaks?

Buy a 5.0 Mustang O2 sensor = $35 at Auto Zone. I did and it worked perfectly. Use this tutorial to show you how to do it and which part # to get.
