O2 sensor brands?

Need a new O2 sensor on my Renix-era...anyone have a recommended brand?

NTK is by far my favorite brand of O2 sensor.

Any particular reason?

They're the OEM supplier to Jeep and operate flawlessly on the 4.0

NTK has lasted longer than the last Bosch did for me on my '88. Was about a buck more expensive.

Always had success with Napa/Bosch

Bosch for me but I have went with the cheapie for the rear sensor and it works just as well.

Looks like I'll give the NTK a shot. Thanks guys! :thumbup:

After having worked in a chain store and checking the difference between parts, on sensors for engines, your best bet is going with an OEM brand. Whether you go to the stealership, or online, I have had trouble with Bosch sensors in every vehicle I have owned. The worst was a 1990 Honda Accord 4cyl, that when the sensor was put in, the check engine light came back on, and subsequently the fuel mileage went down. Upon further research, I found that the tolerances on the OEM ones are within the specs of the engine computers. Thus when I went to the stealership and bought the $30-40 higher part, I then installed it, had no check engine light, and the fuel mileage went back to where it was when the first one went bad. That's just my take on it, but from my experience and research, the Bosch units are within a range, but not as tight as the OEM ones are.

HTH,

Thanks for the insight Jeff!

Seems like Bosch anything in the last 10 years has gone down the crapper. I went with the NTK.

It is my understanding that Bosch invented and made the Renix OEM O2 sensors, and that is what I bought 4 years ago for my 87 Wagoneer. The 89 is still running the OEM 89 O2 sensor on the 89 Cherokee, with about !24,000 miles now (Bosch).
