Review on Denso 234 4066 Oxygen Sensor by Michael Cooper

Revainrating 5 out of 5

This Denso replacement actually appeared to be of better quality than the OEM sensor

Installed on my 2006 Chevrolet Cobalt LS at about 170,000km. The check engine light said the rear oxygen sensor was bad and I was due for the state inspection. This Denso replacement actually appeared to be higher quality than the OEM sensor. It installed well and I passed the test with no problems. After several thousand kilometers I had no problems.

Pros
  • . Fine!
Cons
  • Could have chosen a newer model
