Question Oxygen Sensors

Does anyone know if it makes a difference to what manufactures O2 sensor you use. I need to do both the pre and post converter sensors. Also, who has the good ones cheap? Thanx

In my experience.......

There does seem to be a difference. AZ has Bosch sensors but i have had serious problems with them. Have the feeling it is a 'you get what you pay for' situation. The pre-cat sensor is so crucial to good engine performance that i would at least buy that one maybe OEM. The post-cat sensor is not at all crucial to engine operating parameters but just to keep an eye on cat condition. Perhaps a low-cost one might work for that one. Might be worth a try. Are you sure yours are defective?? Judd

The last I knew the OEM O2 sensors were made by Bosch, so I don't understand why anyone would consider Bosch to be sub-standard.

Just curious, how did you decide both of your sensors were bad?

Bosch by bosch, champion by champion. I just picked up 6 champions from the dealer and can still see a difference with the single champion plug I picked up at an autoparts store. O2 sensors may be the same deal.

Re: Oxygen Sensors

Its pretty rare that they would both go out at the same time, have you run a scanner yet? My XJ started running like crap and I ran a scanner and found out it was the pre-cat sensor, replaced it with a Bosch that I bought at Autozone and shes running like a champ again.

Re: Oxygen Sensors

I trust Bosch. I'm currently running an NTK Oxygen Sensor (NTK is the sensor division of NGK, as in spark plugs. I'm also running NGK plugs, after Bosch single-electrode platinum plugs- both the Bosch and NGK perform great.) The NTK Oxygen Sensor has held up well, and works.
