Denso 234-9120 Oxygen Sensor (Air and Fuel Ratio Sensor)

Perfect replacement for my 08 subaru forester. Thanks!

2005 Subaru Outback XT experiencing P0030 and P0134 codes. This front O2 sensor installed (passenger front) fixed the issue right away.

Packaging was poor. Box received dented. Slow shipment. No problem with the sensor though.

This is a perfect OEM replacement for a 2007 Subaru WRX - it even has the clips to attach it to the bracket that keeps the wire away from the exhaust header. Much cheaper than ordering from Subaru.

Exact OEM specification for my 2005 Subaru Impreza WRX STI.Exactly as described, and timely shipping. Overall a pleasant experience.
