Up for grabs is a brand new in the box Bosch 4-wire o2 sensor. It's a universal type so it comes with it's own connector (basically you replace your current clips with the ones provided).

Never been used, brand new. Paid 65.79+shipping a month ago. Great for OBD1 conversion, tune-up, etc.

Asking 50$ shipped. Paypal only.

Here's the picture from RockAuto where I bought it. Comes with everything you need to install!

 

Still up for grabs.
