Bosch 17300 oxygen sensor for the 2005-2007 Cadillac CTS V6 2.8L, the 2005-2008 CTS V6 3.6L and other vehicles reads the air-fuel ratio in the exhaust and sends it to the ECU. The ECU uses that reading to adjust fuel delivery, which helps fuel economy and emissions.
- Wideband A/F design measures the air-fuel ratio continuously across the full lambda range
- Reaches operating temperature in under 7 seconds for quick closed-loop control
- Integrated heater element with optimized heater control
- Withstands exhaust streams up to 1,880°F; TSP coating resists vibration, corrosion and contamination
