Bosch 13056 Oxygen Sensor, OE Fitment (Chevrolet, Geo, Toyota)

• Ceramic element with integrated heater requires less power to activate, and reaches operating temperature more quickly than a thimble element
• Improved protection tube provides increased thermal resistance for long life
• Laser weld and Viton sealing system is totally submersible to seal tight and protect against contamination for long life
• Coated threads for easy installation

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.
