🚙 A27678X O2 Sensor Set for Jeep Cherokee Grand Cherokee Wrangler 4.0L - Upstream and Downstream, Sensor 1 and Sensor 2 - 234-4076, 234-4078 Review

Easy to install, good price for what they are. They even came with clips on the wires so they could be hung from the original brackets. My O2 sensor code was removed in my '97 Dodge Dakota v6.

Well protected with lids, protective packaging, no anti-size needed. Supplied in a box with instructions. Can't rate the performance yet but it appears to be a quality product.

I only needed one (the one after the catalytic converter but I decided to replace both as it was a two piece kit. This solved my problem as my 1996 Jeep Cherokee barely idled and hard when shut off sometimes My jeep runs like a champ now I drive it 275+ miles a week to work and now I've got several thousand miles with no problems I would recommend this set of oxygen sensors to anyone.

The bottom sensor lasted exactly 23 miles before code P0138 appeared. I checked the wires, the voltage at the sensor is normal. So this is a POS sensor. Will try to see if a replacement can be sent. I don't want to pull both sensors. And I can't pull them out and send them back and wait for new ones because the rest were in the trash. I got them because of the high ratings this piece got. I'll update this once the replacements are installed

I had a constant check engine light that I wanted to remove but decided to fix the problem. So far I've only changed the input, but the improvement in driving performance has surprised me, and of course the check engine light problem is gone. On my 1998 Jeep Wrangler the replacement was fairly easy, obviously modified before because it came loose fairly easily which ended up being a 15 minute fix (but I had the right tools). Next time I jack it up I'll switch the back.

I have a '97 Jeep Cherokee. The body and interior of the car have clocked 253,000 miles. Every detail, down to the nuts and bolts, is new. One of the last things I wanted to tackle was the exhaust system front and rear including a new catalytic converter, muffler and O2 sensors. I am happy with them and will be using them again in a minute. I'm having a hard time estimating mileage as I've only driven the XJ about 200 miles since O2 sensors were added. *** I will say that it is much easier to…

I have found that some Dodge vehicles listed as compliant with this part do not require a second sensor. My mom's old Dodge Durango only has one oxygen sensor, not two. I thought I was missing something as I found and installed one but couldn't find the other, but no, some models use two and some don't depending on the finish and when exactly it was made (and in which condition it was). did). Per). However, I could have easily found this before ordering as I noticed many separate packages that…
