Oxygen Sensor for 2012-2018 Ford Focus - Bosch 16246

Bosch 16246 oxygen sensor for the 2012-2018 Ford Focus 4-cylinder 2.0L measures the air-fuel ratio in the exhaust and reports it to the ECU. This Bosch O2 sensor is a heated, narrow-band switching-type unit for the downstream position.

• Switching-type design that sends air-fuel-ratio readings to the ECU for combustion control
• Integrated heater element and TSP coating to resist vibration, corrosion and contamination
• Handles exhaust gas temperatures up to 1,880°F
• Reaches operating temperature in under 10 seconds for quick closed-loop control
