Key Features:

  • 4-wire heated design for rapid sensor activation and accurate readings

This sensor features Bosch's precision ceramic element technology, known worldwide for quality and performance. The grey connector housing and approximately 11.6-inch cable length ensure proper fitment in post-catalyst positions. Each sensor is engineered to meet or exceed OEM specifications for long-lasting reliability and optimal engine management system performance.
