O2 sensor (Bosch or Nippon Denso)

[Chris]

Ok, I am looking for opinions based upon peoples real world experiences with changing their O2 sensors. My daily driver SVX that sat for many years with a broken tranny from a previous owner needs both O2 sensors replaced. I can get the Bosch for $50 or the Denso for $100. Has anyone had experience with either and can I get away with getting Bosch ones for half price? I am after all a broke college student (uhh.. make that system administrator) .

Any information would be greatly appreciated and likely informative.

i have not yet purchased new O2's for my car but ones i have put in other peoples car always seems to come down to this... you get what you pay for

To make the installation easy, buy the O2 sensors with the plugs, not the ones that need splicing.

The Bosch plug and play for $91.00, from Advance Auto Parts seem to be as good as the $103.00 factory Subaru O2 sensors.







I HATE the splice universals.

Yikes, I was quoted over $200 each by the idiots who safetied the car when I bought it.

If the O2 sensors are shot, the check engine light comes on, correct?

Replaced mine yesterday night with the universal Bosch splice style of O2 sensor. Took about an hour total to do the whole swap and splice. Very easy with the help of a 7/8 and liquid wrench.

Wire colors match up from the Bosch sensor to the OEM plug the same?
I have an impact rated O2 socket and a large rattle gun if needed.

You definately want to use a hand wrench and liquid wrench/PB Blaster.
An air gun will most likely spin out the threads.
Take your time and go back anf forth, working the O2 sensor out.

Yep, exactly the same. I also agree with svxfiles, use a hand wrench and work it slowly around with the penetrating fluid. Takes hardly any more time and effort than with an impact gun.

Are the Denso sensors plug and play? And are they any good?
Thanks
