Your cart is empty.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 damage 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.

Purchased to replace an aging sensor. It worked great for 3 days, but all of a sudden the engine was starting to stall out. Connected scanner to find fuel trim was going to -30% for short and long term due to O2 sensor reporting a rich condition. Had to reinstall the old sensor and car ran like it should again. Probably will buy OEM sensor from GM dealer.

Used this oxygen sensor as a replacement on my 2006 Chevy HHR. Worked like a charm. Cleared my engine code. This upstream sensor may cost more than others you will find on Amazon, BUT you will mot have to worry about its quality....and it still beats the price you will pay at a parts store.

I did a lot of research before purchasing this. I installed this on a 2006 Saturn ION and after a bit of messing around the engine, I found that the worn out one was before the catalytic converter, which was behind the engine. I swapped it out fairly easily, but it took me longer because i had crappy tools. The original was tightened down pretty well, but eventually gave in. Once I installed this one, it took about 3 weeks for the check engine light to shut off, but it did eventually cycle off and after a month of driving with it, the car has definitely gotten better gas mileage.

Great replacement for the upstream Oxygen sensor on my 2006 chevy cobalt. Since it did not have pictures, I felt obligated to add my own in so others can see before they buy. There wasn't many details on the product page, so I hoped I had the right part. For my car this was replaced the upstream oxygen sensor before the catalytic converter, really easy to swap out with the bad one, so far so good with the sensor.
