Your catalytic converter does a great job of keeping pollutants out of your car’s emissions, but it can’t do it without a little help from the oxygen sensor. The readings that the oxygen sensor takes help to adjust the fuel and air mixture in your combustion chamber. This helps your BMW Z3 to get its best possible combination of fuel economy, low emissions, and maximum power.

If your fuel and air mix is running too “lean”, you may experience lower gas mileage, because your fuel is passing into the exhaust unburned. Your BMW’s emissions will then go way up.

A fuel and air mix that is too “rich” causes a car to idle roughly and be sluggish. Your spark plugs may also get damaged because of the fitful starts. Either way, ignore it and be prepared to spend more money on your Z3 than you would like to. We have the oxygen sensors you need to keep your car running like it should in our online catalog. Keep your Z3 running efficiently and smoothly like it was designed to do with a new oxygen sensor. All of our oxygen sensors are in stock and ready to ship to you with a click of the mouse.
