O2 Sensor

It looks exactly like it did in the picture that it was displayed on. Came out of the box perfectly!

1 out of 2

Bought two to replace both at the same time. One was bad out of the box. My mechanic obtained one locally so the work could be done all at once. Will be returning bad part for refund. This is the first time a 1A Auto part has been defective out of the box.

I have a 2015 chevy equinox 2.4l. I removed the upstream o2 sensor, but it has a male end not a female end. It looks like the one in the picture however. Can this come with a male end?

Yes, according to the information you provided, this part will fit your vehicle. We do not have a different type of connector available at this time.
