17351 Premium Original Equipment Oxygen Sensor - Compatible with Select Audi A4, A8, TT, Quattro; Bentley Continental; Volkswagen Beetle, Eurovan, Golf, Jetta, Passat, Phaeton, Touareg

This was a direct replacement for my edelbrock Pro Flo 4 efi system. Package arrived on time and was a genuine Bosch item. Install was straight forward, and product is performing as intended.

Worked perfectly a replacement for my PLX setup.

Fits great. Plugged right in. Came in oem Bosch box. Very happy with it for $20.

Good quality works great great value

This product was wrong part for my vehicle. But I was able to place it with another that fit. Thank you.

I've tried the generic ones and they don't last. Buy the brand name.

Do not buy wideband sensors through Amazon. First I purchased a knock off wideband sensor to save some money and it was a waste of time. Did not work at all, so I sent it back. I then ordered what I thought was a "real" Bosch wideband sensor and it too didn't work, AFR was all-over-the place. I replaced a lot of parts thinking the sensor could not be the problem. So, I switched to a used backup Bosch sensor I had from another project, and behold the car ran beautifully. I use Amazon for many different types of daily use items, but I won't be buying electronic critical sensor auto parts that could destroy an engine that required both financial and sweat equity to build. Buyer beware!

Original package i used in my 2007 honda civic si turbo, perfect reading

Arrived exactly as planned & described, highly recommended! Only thing negative in this purchase is Amazon says that they honor the factory warranty, but they don't tell you what that is. After ~20min on the phone with Amazon they still couldn't give me an answer. So they get an F for having their consumers research that basic information for them......... After I called Bosch directly I was told that it is 1yr; just an FYI.

Fonctionne super bien et a première vu est de meilleure qualité que celle de AEM!!

Works great with my KTM Duke 790

Conforme alla descrizione, arrivato in imballo originale e in tempi brevissimi.

My car had very poor driveability but no check engine light. Weird. Some online searching pointed to this part being faulty. I removed it from the vehicle and searched for the BOSCH part number, and came up with this replacement. Much less expensive than the Genuine Porsche part, but the exact identical item, at 1/3 the cost. Free fast shipping included too. I ordered it on the Saturday of a long weekenhad it in two days. Problem solved. Thanks, Amazon!
