5Denso Oxygen Sensor
By William T. Drake
I used another brand and every few hundred miles I had the same oxygen sensor code. Replaced it with the Denso product and after a few thousand miles, no more products. Will always specify Denso in the future.

42003 Camry Bank 1 Sensor 1
By Father-knows-best
This product was slightly different (longer wiring). It is an A/F sensor for bank 1 sensor 1 on a 2003 Camry V6. The B1S1 sensor is located on the firewall side. the product arrived earlier then stated and fit perfectly. so far I am impressed. I would recommend taking the old sensor out first and attempt to match it to the same type sensor.
