Denso 234-9097 Air Fuel Sensor

Internal dash on a 2012 Subaru Outback 2.5i lit up like a Christmas tree. The CEL light was illuminated, and the parking brake light was flashing. Scan tool determined that the front oxygen sensor had to be replaced. A google search revealed that this is the OEM part that is used. After replacing it, the car has been running smoothly and no more CEL illumination.

This was the correct part for my car, which was my main concern ordering car parts from Amazon. The parts appears to be equal or better quality than the original and installation was smooth. Anti-seize compound is included in the package.

Prefect fit. Came with anti-seize packet. Fixed air fuel O2 sensor codes. You should probably get the "ARES 70039-3/8-Inch Drive by 7/8-Inch (22mm) Offset Oxygen Sensor Socket - Wire Gate Accesses Sensor" to help break the old one loose.

This worked well and solved my problem. Cleared my engine codes and went on my way. Easy install. I also believe this is the part that came installed on the vehicle, or the original had been replaced with a DENSO. (2012 Subaru Legacy)

Changed my old sensor with 150,000 on it. OEM fit and no codes.

This item is an exact replacement for the OEM sensor.

Great product for the best price I could find.

After installing this replacement O2 sensor I lost 3 mpg. This is unacceptable. I guess you should go with OEM to get a proper product.
