FAQ:

Q: Is the O2 sensor plug the same as the Hex plug?

A: Previous mechanics had stripped out the original hex plug. Used vice grips and a hammer to remove. Since the O2 sensor plug had the same specs and was basically the same, a new crushable washer and some antiseize compound seems to have done the trick and saved a few bucks off the OEM plug.

Q: Is there an O2 sensor plug for BMW R1200GS?

A: BMW r1200gs Made of good strong material. Threads right into the 02 sensor hole perfectly. I’ve used these on several different makes and models and they’ve all fit as stated. I purchased a replacement exhaust manifold that had two O2 ports instead of one. This plug fit exactly as expected and has not caused any issues.

Q: Where is the O2 sensor in the engine?

A: The engine computer is responsible for calculating how much fuel the engine needs based on the amount of oxygen in the system, and it relies on a good O2 sensor to function properly. The sensor is mounted in the exhaust manifold to monitor the amount of oxygen in the exhaust.

Q: How does a wideband O2 sensor work?

A: Wideband/Air-Fuel sensors perform the same function as a regular O2 sensor, but they precisely measure the amount oxygen in the exhaust rather than just switching between rich (too much fuel, not enough oxygen) and lean (too much oxygen, not enough fuel).
