Brand new, Genuine Bosch OEM oxygen sensor. Exposure to carbon, soot, harmful gases, antifreeze, chemicals, and thermal and physical shock will shorten the life of an oxygen sensor. A worn sensor could result in reduced gas mileage, poor engine performance, and/or emissions test failure. That's why checking, and if needed, replacing a worn-out oxygen sensor is an important part of every routine tune-up.
