The Bosch oxygen sensor utilizes a mix of zirconium and yttrium oxides and other elements to form a tough base that withstands the intense stress to which oxygen sensors are subjected. Each element is incredibly strong for best-in-class performance and maximum service life. From overall sensor design to the critical ceramic element, Bosch is known worldwide for quality and performance.

If your engine is throwing a check engine light for a bad oxygen sensor, it is important to replace it. The O2 sensor measures the amount of unburned fuel in the exhaust pipe to adjust fuel mapping for less emissions and better fuel economy. When malfunctioning, your MPG and performance can suffer. Keep your engine running efficiently, restore your performance and gas mileage!
