O2 Sensor Difference

I was looking at O2 sensors for my '08 WK with the 5.7L. I know there are for of them, two upstream, two downstream. Are the sensors the same for all four locations or are there different ones for different spots. What are the part numbers? RockAuto had several but I didn't know which to get.

I'd have to say they're all the same on the vehicle. Pick the brand or price you want.

Some use different sensors for up or down stream, looks like this isn't one.

Only use NTK(Chrysler OEM O2's) O2's in Chrysler vehicles.What ever you do stay away from Bosch O2's as they have known issues when installed in Chrysler vehicles.

I agree ^^ NTK only
The 05 and 06 HEMIs have different part numbers between the upstream and downstream sensors .My parts manual agrees with that . Looks like they changed that in 07 for some reason.

I would recommend genuine Mopar sensors only. They are electrically correct for your Jeep. There have been numerous issues with aftermarket sensors, even when the manufacturer is the same one that makes them for Mopar.

PM me or email me if you'd like a price. The Mopar sensors for the WK are not too expensive and I discount them 25% off what you'd pay at the Jeep dealership.
