Rock auto? That a website? I was just gonna go down to carquest ( a local chain) an ask em what they got

 

Wowza they have a lot of different ones

 

Denso or Bosch IMO.

 

here

 

I have 4!! *********, the ones I was lookin at are $40 a piece also I'd like to bring up that in this pic in a dis cap... I have coil packs... Wrong engine?

 

This is the 4.0, and i think this one has 4 o2 sensors because of cali emissions, but not all have 4 o2 sensors.

 

Well I'm in Cali but the rig started its days in Colorado

 

Mine came from washington and it has only 2 o2 sensors. Good luck.

 

Thks! My luck is terrible so I prolly have an additional 5 aftermarket installed. Ones gotta be by my cat so ill check that one out first. Can u visually see that they are bad or what?

 

Make sure you buy the correct o2 sensor for the up or down stream o2 sensor. If your o2 sensor looks like it is "burnt white(my best description)", then it is most likely bad. Or you will have to get a multimeter and test them.

 

Kay, Thks for the tips! Need all I can get haha

 

So been doing some research and I'm quite confused. I went to my local car quest and they suggest Bosch part number 13280 for upstream o2 sensor, I looked on rock auto and they have that product as a downstream sensor (for much cheaper I might add) what gives?? There's soo freakin many different ones I have a Cali emissions 2000xj sport. Anyone wanna help point me in a right direction???

 

I have a 2000 with four one year ago I was able to buy four Denzos on Amazon for $19.99 each
