BMW Replacement Wide Range Air Fuel Sensors
No automobile boasts a history of enduring precision that stands up to cars from BMW and that reputation is for good reason. Protect your vehicle's systems by buying only the most reliable high-quality engine parts. When you drive an automobile engineered for high performance it requires top quality auto parts. The Air Fuel Ratio Sensor has a key function: getting the engine to work productively without causing unnecessary emissions.
If your car's ratio of fuel to air is too low, poor engine power will be the result; on the other hand, a too-rich fuel mix can lead to damage to the engine and excessive unburned fuel from your car's exhaust. Because an inaccurate Air Fuel Ratio Sensor can hurt your wallet by running too rich or too lean, fixing it will be economical in the long run. A properly installed Air Fuel Ratio Sensor monitors how much oxygen is feeding your BMW's cylinders. Your Air Fuel Ratio Sensor works in combination with a car or truck's CPU to determine whether or not the air-fuel mix provided to the motor requires to be altered. Your car's Air Fuel Ratio Sensor calculates the air-fuel levels in the motor, keeping them within the suggested ranges for optimum performance.

Some of our Customer Reviews
Very Satisfied
Reviewer: Said Taleb
No one I called had the oxygen sensors for my BMW 535xi for less than $250 each. I found them both on the Parts Geek website for the cost of just one of them.
