Bosch 17014 Oxygen Sensor, OE Type Fitment

Bosch advanced ceramic technology affords best-in-class performance. The ceramic element in Bosch planar type oxygen sensors is created by printing multiple layers of protective, insulating, adhesive, and conductive materials, including platinum, on several ceramic layers. These layers are pressed together and fired in a kiln and the resulting element is lightweight and incredibly hard and strong, for best-in-class performance and maximum service life.
