Denso 2344256 OXYGEN SENSOR

Exactly the same as "oem" acdelco. Denson makes them for acdelco. Worked perfect. Removed the MIL/CEL from my 2011 silverado 2500hd.Would recommend and buy again.

The product was an exact fit, same as factory. No issues, plug and play.the product was shipped quickly, and the price was good.

Replaced my downstream 02 sensors on 13 gmc 2500 perfect and code went away

Perfect for 2013 chevy Silverado 1500. Plug and play. Comes with plugs and antiseize compound. Plug and play

At 130k miles I noticed sluggish acceleration, poor idle, then the check engine light come on. Checked it out with my OBD2 Scanner and found the driver side (upstream) oxygen sensor was bad. I bought this truck new so the bad oxygen sensor was original. After replacing the (upstream) sensor with the Denso 234-4668 Oxygen Sensor my truck is running smooth again.Since all the sensors were original with 130k miles I decided to replace the downstream sensors and purchased two of these Denso OXYGEN SENSORS. I read that the oxygen sensors should be replaced around 75k miles so it was probably time to replace them all.This replacement sensor looks a bit different than the original, however, fits and works like the original factory sensor.These downstream oxygen sensors are very easy to replace.Overall, these Denso Oxygen Sensors work well at a reasonable price.

Put it on an 08 avalanche 5.3. Work good For about six months until I put some water in my gas tank and It did something to all 4 sensors. I guess all the backfire and it was doing when it fouled out one of my injectors. It’s best to replace him how are you be replacing cats like I did. But 300,000 miles later something had to give out.But the old truck run good with the new sensors upstream and downstream. I’m replacing the parts one by one what is cheaper than a new one

Exact OEM fit for my 2011 Chevy 5.3L Silverado LT-4x4.-Fixed downsterm O2 Sensor-Fix Engine Light went out and has not come back on.

About a month of it working normally and now not so much.. Time to replace with one from parts store

Perfect fit and fix bank 2 Sensor 2 on 08 silverado. Cleared codes and all fixed thank you. Great price for quality part

Perfect fit for my 2009 Suburban, with some heat, penetrant and some patience took 20 min to remove old one and install new one. Cleared P0141 code, all good now.

Worked fine, saved me some cash over buying it from a local jobber. One thing I noticed though is that the protective sleeve over the wire is too short, I had to cover part of the wire with some electrical tape.

Changed the original Sensor to this new Denso Oxygen Sensor on my 2012 Chev Silverado, due to previous error codes indicating Sensor stuck open, Sensor Stuck closed, and Sensor No Signal. Installation of the new Denso Oxygen Sensor resolved the Code issues and the Check Engine Light is no longer illuminated. Wish I had purchased a special socket for removing the old Sensor as it could have made the job easier. Had to heat the outside of the threaded welding boss on the exhaust pipe with a torch in order to free the old (seized) Sensor. Also, after removing the old Sensor and letting the welding boss cool down I used electronic spray cleaner to clean the contacts on the existing vehicle wiring connectors for the Sensor. From my experience so far, I would definitely purchase Denso Sensors in the future. NOTE: If purchasing a special socket for removal, make sure to obtain one that fits the Sensor on your vehicle. I used a 7/8" wrench per a 2012 Chev Silverado video presentation and the 7/8" was a very sloppy fit (a 13/16" wrench was too small). Luckily it got the Sensor removed after heating the welding boss; Sensor must have required a Metric size wrench that I did not have available.

It fixed the problem
