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 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.

Feel like something is wrong with my Jeep... there's not a Check Engine Light glowing on the dash :-)I had a P0038 code thrown by the system. Replaced the damaged O2 sensor and after about 30 min of running the code went away.

Purchased for my dodge grand caravan that was throwing codes for o2 sensors. I got two of this brand for downstream and two of another brand for upstream. Didn't clear codes. Then I realized the other brand was mislabeled and actually bought 4 downstream total. So replaced those two with ones from Napa. Still throwing code. So now return window for all 4 is closed and I have to spend MORE money replacing these two...

I replaced working rear O2 sensors to possibly see improved gas mileage. The sensors worked great initially and delivery was great.That was about 15,000 miles ago and this one failed. I thought buying a Bosch product would have been a no brainer.Fortunately I saved the old ones and everything is working.How can I get a replacement for this failed unit?

Packaged and delivered without any damage to the product. High quality items to replace the original stock O2 sensors. Quick and easy to replace and the plug is a standard universal plug connector, so it needed no modifications. I really like the anti-seize lubricant that came with the sensor on the threads and ready to screw-in to the cats.

Fit my 2005 jeep liberty, cleared the P0138 code i had. Old sensor wiring fell off its harness and the wires melted against the exhaust, perfect fit and functionality.

Great Price and fast delivery. I got (4) of these (upstream and down stream) and what a difference in response and performance. My truck has about 210,000 mi. and I change these about every 80k. My truck was feeling a bit sluggish so I changed them early. I didn't have any error codes, but I know the signal from the sensor had to be slowing down. The engine now idles smoother and runs much stronger. The price and delivery time was good enough that I will be buying these for my 2007 Chrysler Aspen 5.7 Hemi.One item to note: there is a difference in the connectors on the upstream. I already knew this (the upstream is a different part No.), I just cut off the original and attached it to the new one. The down stream was a perfect match.
