O2 sensor / Need Pelican Assistance

Hey there,
I was wondering if the O2 sensor you list here:
http://www2.pelicanpartsexpress.com/catalog/images/fuel_injection/new_images/kn_o2_sensor.jpg
is an OE replacement.
What is different between that part and the Bosch part here?:

By the way, any personal opinions on the difficulty of the reaching the 1/3 pre-cat O2 sensor would be appreciated!
Thanks!
