Im going to be replacing my 165,000 miles oxygen sensors soon on my '98. I have had a problem with part numbers on these things, as I keep getting different results from different places. The precat O2 sensor wasn't a problem, and placed an order earlier today. However, for the postcat, I'm getting inconsistent part numbers. When I look on Autozone or AdvanceAuto, the Bosch part numbers show up as part #13138 however, when I go directly to Bosch's website, it states the postcat sensor is part #13272. I did a little research on this, and sensed some confusion, however, never found a definitive answer. I'm curious as what the difference is between these two sensors, and did either Bosch or Autozone/Advance screw up if there is a difference. I'm looking for someone with some knowledge regarding this issue, and lend me some insight as to which sensor to order. I would greatly appreciate it. The part numbers from the part finder on Bosch's website can be seen below.

 

I'd suggest you order a NTK sensor. NTK is part of NGK and is the original supplier for jeep O2 sensors. While I'm sure Bosch sensors are reputable products, many jeep owners report problems with them.

 

Just do the plug and play NTK's from amazon, think both of mine were 60 bucks for the pair. ZERO problems

 

x2 with both above. Go to rockauto.com and get the NTK part number from there and then hit up amazon with that number and you should find what you're looking for

 

I agree with the others. Order NTK from Rockauto. Tough to beat their service and price.

I recommend NTK for 91-01. Bosch specs seem to be a smidgen different than NTK. Many can run Bosch without issue, but for whatever reason, some have troubles with them. Because of that, stick with NTK for 91-01.

Bosch was the OEM supplier for the 87-90 and Bosch works fine for those years.

 

you can get them off ebay for 38 bucks

 

x2- OEM all the way

 

Another one for the NTK. Stay away from bosch on these vehicles.

 

I just cancelled my order on the Bosch 13100 so will be ordering the NTK's instead. I really appreciate all of the insight, by the sounds of it,you all have saved me lots of headache! Thanks guys!

 

Not to brag but we pretty much rock

 

Good idea on getting the NTK's. I could be wrong but I think the part numbers are different based on 49 state vs california emissions.

 

I wont argue with you on that one. It's you guys that remind me why I keep coming back here

The part numbers I found for the NTK sensors are 23151 (precat) and 23099 (postcat). Can anybody verify these numbers for me? Also, where did you guys order yours? Amazon, RockAuto?

 

Yes, 23151 (pre) and 23099 (post) are the correct NTK part numbers.

 

Awesome! Quick responses are the best haha...

Now any takers on best place to order?
