I am new at doing my own maintenance. I am putting in a new O2 sensor (Bank 1 Sensor 1) tomorrow. I borrowed a specialty tool from Auto Zone to remove the old one. Any other advice or tips would be greatly appreciated. Thanks!

Spray wd40 now to let the oil penetrate. So tomorrow it will be easier to remove.

What brand is best for O2 sensor replacement?

Everything removed pretty easily. I bought a Bosch for replacement and the plastic part will NOT clip in. Any suggestions?

No no no. Stick with a motorcraft; bosch ones can give problems.
bank 1 sensor 1 is passenger side front sensor.

I gave up on the Bosch and got another sensor from the Ford place and it went right in. I returned the Bosch. Made it through my first repair! Thanks!
