ok, so i did some research. It looks like my 2000 Sport has 4 oxygen sensors. I'm going to replace all of them with Bosch, went down to oreilly auto parts to get 'em and ran into a problem. There's more than a few different part numbers, and i don't know which ones to get? Also, once I have the correct part numbers which one goes where? Thx in advance, this forum rocks!

 

You may gain some info by looking at www.rockauto.com.
There are a number of different ones, but they list all of the Bosch units. Their description can sometimes be vague, but by comparing descriptions you can often figure out what you need.

Plus, Rock Auto is usually about 40%-60% cheaper than O'Reilly/AutoZone/NAPA, etc. I've bought dozens of parts from them for my '98. Shipping is fast, and I haven't had a single problem with anything I've bought from them.

 

Rockauto is great i buy anything i dont need "right now" from there

 

CONRAD, I am a product specialist with Walker Products, a manufacturer and worldwide distributor of oxygen sensors. I’d be happy to figure that out for you. What size engine do you have in your Cherokee?

 

Is the 1998 Cherokee the same?
I thought there was only 2 on mine... total.

I guess I need to take a closer look.

 

Here ya go....

 

Thanks Ken,

Mine is a NON California XJ

pretty sure I only have 2 total.

you got any images of the non Cali xj?

 

No image, but you need NTK 23151 for the upstream (pre-cat) O2S and part number 23099 for the downstream (post-cat) O2S.

 

Thank You!
