## Description

Denso 234-4012 Oxygen Sensor, Original Version

Review: Denso siempre la mejor calidad
Review: I needed oxygen sensors for my 2001 Chevy Blazer. My truck has 3 oxygen sensors, and one after the CAT went bad causing rough idle and increased fuel consumption. Also, the engine light would come on almost everyday, after I clear the code. All 3 oxygen sensors are the exact same on these trucks, so if you have a 1998-2005 s10 with the 4.3 vortec, or a 1998-2005 Blazer with the 4.3 Vortec, this oxygen sensor will work, and you can buy three of these to change all the oxygen sensors. I decided to go with these Denso oxygen sensors because Denso is reputable, and makes great OEM parts that fit and function just like OEM. I have never had issues with Denso parts, ever. These oxygen sensors also came with graphite anti-seize already applied to the threads, which is nice, but copper would have been a better choice for exhaust components. I just needed one oxygen sensor, but decided to just replace all 3, since the original ones were all 24 years old. Took me 30 minutes to replace. My truck now runs and idles much smoother, and based on the scan tool reading, it seems these o2 sensors work just like it should!
