BOSCH 17178 Premium Original Equipment Oxygen Sensor

Calidad señores es histórica la calidad de Bosh. Lo instale en mi Audi a6. 2.0. Y. Todo como siempre. Súper. Hoy día la calidad es indiscutible

replaced the original sensor seamlessly, this one is the wideband type, not a normal narrowband sensor

Put that this Bosch in and it passed smog (previously got a P0430 error). I went through 2 sensors (both said they fit my car) before figuring that you need to stick with what works. My original O2 Sensor was discontinued (number is stamped on the side of the sensor), but research from the web said this was the replacement number (Bosch Oxygen Sensor - 17178) . Previous to that, the sensors, although looking identical and fit the connector, would give me an error - P2234. Hope this helps.

Connector fits great but wire length is much longer than OEM. I just folded the wire almost like in the packaging picture and used the enclosed zip ties for a neat fit. Extra zip ties came in handy when I replaced the downstream Oxygen Sensor which did not include and extra mounting parts.

2014 Audi allroad 110k miles Perfect oem fit, instantly cured my cars stuttering at 2k rpm You'll need a large bar to remove the old one though since it's on so tight and probably frozen in place , at least I did. Otherwise it took a few minutes to install.

I installed this in sensor 1 bank one of my Lamborghini LP560 it was perfect! I installed it through the wheel well

I had DTC P0030(O2 heater circuit not working properly) Swapping out sensor fixed the problem. No need to have the new sensor be "learned" by ECU.

Product as described. Bought used and only package was torn. New product never been used

Fit perfect and easy to install. Go to your local auto parts store and buy the proper Oxygen sensor socket ($10-15).

La marca bosch es de excelente calidad, de inmediato soluciono mi problema, espero que cumpla con el tiempo establecido de duración.
