Bosch ceramic technology affords best-in-class performance. Driven by the need to meet U. S. EPA requirements for lower exhaust emissions, Bosch developed the revolutionary planar sensor. The planar sensor "lights off, " or reaches operating temperature, in approximately 10 to 12 seconds. That's over two times faster than a conventional thimble type sensor. This quicker light-off time reduces emissions by over 50% during the cold start phase, when harmful emissions are highest.
