## Overview

The Bosch 16121 Premium Original Equipment Oxygen Sensor is engineered for select Audi A4 models, featuring a durable stainless steel body, fast-acting heater, and factory-tested quality assurance, ensuring optimal performance and longevity.

## Description

Every Bosch Oxygen Sensor benefits from the technological and manufacturing experience gained from decades of production, since first inventing the Oxygen Sensor in the late 1960's, ensuring long-lasting, superior performance that you can count on. Bosch Oxygen sensors are 100% tested for full functionality, resulting in a seared appearance of the protection tube, to ensure every Bosch manufactured sensor meets Bosch's rigorous standards for quality and performance. Exclusive double laser-welded stainless steel body is totally submersible and sealed tight to protect against contamination from exhaust emissions — ensuring a longer sensor service life. Fast-acting heater optimizes sensor operation on Planar and 3, 4, and 5 wire Thimble type sensors allowing the oxygen sensor to reach its operating temperature quicker – within seconds – for optimum performance. True Direct-fit OE connectors and harnesses, along with threads pre-coated with anti-seize compound right out of the box, make installation simple and hassle-free. It’s critical that oxygen sensors are replaced at the suggested intervals provided by vehicle manufacturers before the sensor fails. Following the recommendations will prevent long term damage to a vehicle’s engine, reduce harmful carbon dioxide (CO2) emissions and save money when refueling your vehicle.

### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Working fine...no prob..
  

*by C***X on Reviewed in the United States on August 29, 2009*

Replaced both O2 sensors on my VW Golf after getting DTC for O2 sensor prob. Plug n play pretty much with the right tools. Be sure to use a small O2 sensor socket for the sensor on the catalytic converter as the large O2 sensor socket has no room to fit.  Although DTC for O2 sensor gone now, started getting P0422 cat converter code. Probably not the fault of the new sensors...

    Awesome
  

*by M***2 on Reviewed in the United States on February 5, 2011*

When I saw my check engine light come on I was pretty scared because thats always expensive!I took it in to get the error coded read and walked out with 3! Anyway, I was hesitant to fix the car myself as I had never changed an O2 sensor but it worked out great. It was a perfect fit. I didnt have to cut or splice wires. Anyone with a 7/8 wrench, a phillips screw driver, and jack can change this part. I was quoted almost $800 to fix my car and I did it myself for under $200 and got new break pads!
