From the manufacturer
BOSCH Premium Oxygen Sensors
It’s been 40 years since Bosch invented the Oxygen Sensor and began series production in 1976. That same year, the Volvo 240/260-series became the first passenger car equipped with the new Bosch sensor. From there, production grew steadily and the Oxygen Sensor became an essential tool for fuel efficiency and the reduction of CO2 emissions.
To date, Bosch has produced 1 billion Oxygen Sensors. It took 32 years – from 1976 to 2008 – to reach the production record of 500 million pieces, but only eight years – from 2008 to 2016 – to double the production figures to 1 billion sensors. Bosch Oxygen Sensors continue to lead the market with their high-quality reputation; an attribute that has defined Bosch since its inception.
A New Oxygen Sensor Impacts Your Car!
A defective or sluggish oxygen sensor can cause a variety of issues, like decreased engine performance. Replacing a defective O2 sensor helps ensure your engine is constantly monitored and operating efficiently, while maximizing performance.
The ideal air-fuel ratio of a gasoline engine is 14.7 parts air to 1 part fuel, which is known as complete combustion. The vehicle's engine control unit uses an O2 sensor to regulate air-fuel mixture by checking the oxygen content in a vehicle’s exhaust. This results in fuel savings.
The catalytic converter is responsible for removing the harmful emissions from your vehicle’s exhaust. A defective oxygen sensor can cause your catalytic converter to fail prematurely. Replacing a catalytic converter can cost thousands of dollars, significantly more than most standard oxygen sensor replacements.
If complete combustion is not maintained, other chemical compounds can form in large amounts. These include greenhouse gases, carbon monoxide and excess hydrocarbons. Replacing a defective oxygen sensor is the most effective way to control the combustion process and reduce emissions.
What Makes Bosch Oxygen Sensors So Unique?
American Made on Bosch OE Production Lines
One of the largest Bosch oxygen sensor factories is located in the U.S. in Anderson, South Carolina. We have been producing O2 sensors here since 1991 and we currently produce 15+ million sensors annually. Our O2 sensor reverse engineering team is located within this OE facility and is solely dedicated to serve the aftermarket division of Bosch. For oxygen sensors where we are not the OE supplier, we will reverse engineer the sensors and produce them on exactly the same production lines as our OE oxygen sensors. No other O2 sensor manufacturer has this unique capability. Between our OE O2 sensors and our reverse engineered sensors roughly 90% of our annual sales get produced on Bosch OE production lines.
Some customers have noticed a dark discoloration on some Bosch sensors and question if the part is used. Rest assured that this discoloration is the result of one of our fully automated manufacturing processes – one of many processes that we utilize to ensure that you receive a high-quality sensor from Bosch!

DO NOT ATTEMPT TO SOLDER THE WIRES TOGETHER. Oxygen sensor wires are not made from copper. They're some sort of special alloy that simply can't be soldered. You need to use the connector that comes with the part, or use heat shrink butt connectors. (assuming you have the correct crimping tool)
This video shows how to use their connector system, and has a guide for matching the wire colors correctly.
After checking online for the "Fail Codes" listed on the Smog Test receipt, the codes pointed to the "Downstream o2 Sensor (Oxygen Sensor)" making the fuel mixture too rich. So I called a local Smog Repair shop and I was qouted $220 dollars to replace the part. My former brother in law who had his own auto repair shop told me long ago that mechanics get a 50% discount off list price of new parts, but always put the list price on your bill. So I ordered the part from Amazon, and had my local independent mechanic install it. I saved 70% from the original smog repair quote by doing it this way.
This Bosch 15733 Oxygen Sensor came in Bosh box and with a Universal Connector plus Wiring Instructions. I think any weekend mechanic could handle the job within a few hours but.... I am getting too old to climb under a car anymore. The replacement requires Auto Lifts, a standard Open End Wrench, and Wire Crimping Tool. In my case the Universal Connector supplied Did Not Match the one on my car, so splicing the 4 wires to the original factory connector was required. The 4 wires consist of 2 signal and 2 grounds, and had the same color codes as my original wires. Once removed, the O2 Sensor appeared to have a small amount Black Soot around the base of part as a result of running too rich. After installation the "Check Engine" light went off.
The one thing that I havn't seen in the Amazon Reviews is that my mechanic had to Re-Set the Car Computer. He also told me I had to drive 60 Miles More so that the car computer could re-evaluate the "New o2 Sensor" in full cycle. If you re-test right away, you will FAIL the Smog Test. This is because the car computer retains the old sensor data plus adds the new sensor data, and averages them both until the car computer re-sets again in 60 miles. After that I had the Smog Station re-test my car, and Pass it did.
IMPORTANT: On my car there are both "Upstream" and "Downstream" o2 Sensors. Make sure you Evaluate The Smog Test Fail codes carefully and Order The Correct Failing Sensor.
I hope my review helps, you Do It Yourself-ers should Save Even More!
If it works as intending, after using alternative connectors, I may update this review to a couple stars.
If you are replacing these on your 335i keep in mind there was a software update that may be causing you to not pass smog, a new oxygen sensor may not fix this issue for you and you need to go to your dealer for them to apply the recall software update.
