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.

I bought a budget wideband with the budget sensor knowing I only needed the gauge. The cheap sensor was slow to respond. This one is much faster and I believe probably more accurate as well.

I figured shoot why not just a few bucks more for the brand name ones figured they would be much better but I Will not buy again will go back to the off brand I am used to as one of these brand name one’s installed and started the truck ran great till it went into closed loop and started using the o2 for fueling and truck set a check engine light calling for +40%fuel needed and started back firing after hooking up my scan tool and noticed bank 1 sensor 1 was very slow reacting and that bank 2 sensor 1 was maxing out causing long term fuel trim maxed out as well as short terms caused mas over fueling and back firing. Again will not buy again.

working great in a system originally requiring a sensor valued twice as much.

I have been fight high short term and long term trim levels and found the O2 sensor had no reporting voltage. Everything online said it is not the O2 sensor, but it was. Installed super easy and truck runs like a new truck! Way cheaper than the auto parts store too!

Sensor appears to be great quality but the parameters that the sensor operates is not compatible with the ecm. I have also heard from other guys i have spoke to they have had the same issues with bosch sensors and their compatability with gm products. Instapped and removed so coupd not be returned. Buy a denso if you need an o2 sensor.

It's a new Bosch sensor, I bought this one and the other one because I was getting both O2 codes coming up.I had the front O2 code for a couple years and eventually the rear code started coming up as well.They both made the codes go away, it's been 400 km since replacing. I notice a bit of an improvement in performance,and a little bit on economy. In the winter sometimes I'd smell gas, maybe because of the sensor making too rich ?

I have a 2001 Honda Civic LX coupe (engine code D17A1 stamped on the engine) and this is not compatible, even though I've verified fitment with Bosch and other sources. I'm replacing the upstream O2 for better fuel economy and driveability (car has no issues prior) and this sensor failed the next day after installation. Check engine light turned on and it wouldn't give me gas intermittently and luckily I made it home safe. I put back the original NGK O2 and car is back to normal. Don't buy it.

Works as expected. I have a feeling that if you have old sensors, it is best to replace them to get the best out of your car.I had used the Torque app for Android ( and the BAFX OBD scanner) to identify an older knock sensor code and noticed that the O2 sensor wasnt really giving a full range reading. A month after changing the knock sensor, lo and behold, the O2 sensor code comes up (P0136).I looked around the sensor and all the wires looked ok. I reset the code and it came back on.Then I ordered this part and was able to change it with an adjustable spanner and a few hits from the car's tire iron. It is a 15 minute job at the most. Though, you do have to lie down under the car.I expected the light to go out by itself. I was probably impatient and ended up clearing it my self.I notice better driving with the new part and slightly better mileage.

I did a search on Amazon for a replacement oxygen sensor for my 1999 Volvo V70. I used the compatibility checker on Amazon to check the first one I found and it said that it was compatible so I ordered it. Since it was time for my regular service I gave it to my mechanic to install at the same time. He phoned me during the servicing to tell me that it was the wrong sensor. When I picked up the car there was a $42.50 charge for uninstalling the old sensor and for reinstalling it.I contacted the vendor who told me it wasn't his fault since he had no control over Amazon's compatibility checker. Long story short, the vendor took the sensor back and gave me a refund. Amazon gave me a credit for the service charge and I ordered this sensor.When it arrived I decided to install it myself. I borrowed my son's auto ramps so I could get the car high enough to crawl under. I put the car on the ramps in the garage one evening so it would be cool by the next morning. I did not have the sensor removal tool but thought I would try to remove it using an adjustable wrench. I put a work light under the car and scooted under just behind the left front wheel (driver's side). The sensor is located just in front of the catalytic converter. Although I couldn't get the wrench squarely on the sensor I was able to get a decent grip on it and gave the wrench a hard push. The sensor moved and came out easily. It may have helped that my mechanic had taken it out recently.The wire cable from the sensor runs through a little plastic fastener that may be popped out if you are careful but if you break it, a wire tie works fine. The electrical connector is easily reachable from above. It took me a while to figure out how to disconnect it but finally discovered a small slot into which I inserted a very small screwdriver and the connector popped open. Insert the screwdriver parallel to the wire cable at the top end of the connector.It is a good idea to screw the new sensor in before you connect the wire cable. Otherwise it will get very twisted. Make sure you use the fastener or wire tie to keep the wire cable away from hot surfaces.When I started the engine the "Check Engine" light came back on so I thought I would have to have it reset. I wasn't able to do that right away but after a few starts and driving 20-30 miles it went off. Before I replaced the sensor I was getting about 10 mpg but now it is back to the regular 25-30 mpg.
