REPAIR KIT FOR 1785A

Bosch Switching-Type Oxygen (O2) sensors provide precise air-fuel-ratio measurements to the ECU for improved efficiency and reduced emissions. They are built to withstand exhaust streams up to 1,880°F, featuring stainless steel housings, integrated heater elements, advanced ceramic elements, and TSP coating to resist vibration, corrosion, and contamination. These sensors reach operating temperature in less than 10 seconds and deliver fast signal availability to the ECU, enabling quick closed-loop control for improved cold-start performance and lower emissions. Bosch manufactures over 90% of Oxygen (O2) sensors for the North American market out of Anderson, SC.
