Bosch Oxygen Sensor P/N:17250

Keep the engine's air-fuel control dialed in with the Bosch Wideband A/F Oxygen Sensor 17250, an upstream (pre-catalyst) sensor that continuously measures the exhaust air-fuel ratio across the full lambda range and feeds that data to the ECU for accurate closed-loop mixture control. It installs as a direct-fit replacement for the 2018-2020 BMW M5, the 2020 and 2022-2025 BMW M8, and the 2020-2025 BMW M8 Gran Coupe, all with the V8-4.4L engine.

• Wideband precision: delivers high-resolution, real-time air-fuel data across the full lambda range, giving the ECU far more detailed feedback than traditional switching sensors so it can finely trim the mixture.
• Fast light-off, heated: the integrated heater reaches operating temperature in under 7 seconds for quicker closed-loop control and cleaner cold starts.
• Durable build: stainless steel housing, advanced ceramic element, and TSP coating rated to withstand exhaust streams up to 1,880°F, resisting vibration, corrosion, and contamination.
• Easy install: threaded M18 x 1.5 body with a 22 mm hex and pre-applied conductive anti-seize on the threads; wiring harness included, mounting bracket not included.

Backed by a 1-year, unlimited-mileage warranty for non-commercial passenger cars and light trucks. These applications use two sensors per vehicle; the sensor is sold individually, so order the quantity your repair requires. Country of origin: Germany. Manufacturer part number 17250.
