How to choose the correct O2 sensors

[hcch]

Hi I am experiencing high fuel compsumtions on a 2007 Limited KJ, I have never change any of the O2 sensors.

More Information for NTK 23159

That is the option I have in mind, the thing is the I undestand I need 4 2 on each side, but I do not know if this option will fit on all 4 places?

Also if there is any better brand that you may suggest based on exoerience I will appreciate it.

That is the correct sensor.
It will fit all positions.
Have someone with a code reader check for codes, to see which sensor is faulty,no need to replace all sensors.

thanks for your kind replay, the car has just left my old trust mechaninc he overhaul the ****** service it replace the front struts but my daughter complains about the car drinking 2 much gas I use low octane on it. and since the sensors are the OEM ones since out the dealer when new back in 2007 I belive it would do no ham.

Also tha last sparks I change were some iridium and I think to swap them fo the Ruthenium ones to see if that can also help the gas usage.

Jeep KJ likes copper core NGK ZFR 6F-11G gap set at .040.
Jeeps have never been famous for good gas milage.

Check the MPG with the other guys on here before you buy any parts, it's a 2 ton truck with the aerodynamics of a brick....

I ran autolite double platinum in the 2006 for a couple years and it didn't affect the mileage. Wasn't any change when I went back to the copper plugs either
