Oxygen Sensor for 1990-2003 Ford F-150 & More - Bosch 15717

Keep closed-loop fuel control accurate with the Bosch Oxygen Sensor 15717, a narrow-band, heated switching-type BOSCH 02 sensor that reports exhaust oxygen levels to the ECU so it can trim the air-fuel ratio for stable combustion control. It drops in as a direct-fit replacement across a broad range of listed applications, including the 1997-2003 Ford F-150 [V8-4.6L], 1995-2010 Ford Explorer [V6-4.0L], 1996-2010 Ford Mustang [V8-4.6L], and many Lincoln, Mercury, and Mazda models — see the Buyer's Guide tab for the full list.

• Precise feedback: switching-type sensor delivers air-fuel-ratio feedback to the ECU, helping reduce emissions across a wide range of operating conditions.
• Fast response: reaches operating temperature in under 10 seconds for quicker closed-loop control and improved cold-start behavior.
• Built to endure: handles exhaust streams up to 1,880°F with a metal housing, integrated heater element, advanced ceramic element, and TSP coating to resist vibration and corrosion.
• Ready to install: 4-wire design with M18-1.5 threads, a 22 mm hex, and a round male blade connector; threads arrive with pre-applied conductive anti-seize. Includes a wiring harness; mounting bracket not included.

This sensor is cataloged for upstream and downstream positions depending on the application, including left- and right-bank locations. Quantity varies by engine and position — some listed applications use two sensors — and units are sold individually.
