Review on Optimize your vehicle's performance with the Denso 234-4169 Oxygen Sensor by Shawn Welker

Perfect fit, fixing an issue found by the OBDII scanner. Now the check engine light is off and the car runs much better. If your code says Bank 1, it's the driver's side. If bank 2 is written, then this is on the passenger side. If you are replacing an oxygen sensor, do yourself a huge favor and get an oxygen sensor tool. It costs $8 and you'll be done in 15 minutes. People say that this wire is a little longer. Although it's good. You have more leeway when installing the sensor. Just tie it to another wire and you won't have any problems. Buy this sensor, it's a good deal and it works.
