Works Great on my 08 Silverado 5.3L
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.

Good replacement
Perfect replacement for a 2008 Silverado Bank 1 sensor 2. This Denso was the best value I could find searching a few websites. Almost two months later it is still working fine.

Same as acdelco
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.
