I bought a Bosch 02 sensor Part #13517 from FCP Groton for my wife's 1994 volvo 850. Last weekend I finally had a chance to remove the old one and compare it with the new Bosch sensor. When I compared side by side the old sensor from the car with the FCP Groton Bosch 02 sensor, I have noticed that the new sensor did not have a logo or Bosch name on the barrel and it's marking was not as dark as the old sensor from the car that was probably 10 years old! I will be returning the Bosch sensor to FCP and update you guys.When I first saw the price of their Bosch sensor online, I was already suspicious for its low price $86.77 compared to $120.00 up to $160. from other auto parts stores. Has anyone had the same experience?
