Walker Products 250-241207 oxygen sensor for the 2017-2020 Porsche 718 Boxster H4 2.0L or 2.5L and other vehicles measures the oxygen in the exhaust gas to show how efficiently the engine burns fuel. The Walker Products oxygen sensor is a narrow-band, 4-wire direct-fit unit made for the downstream position.
- Monitors exhaust gases and reduces pollutants
- Electrodes made of a gas-permeable platinum layer
- Measures oxygen so the air-fuel mixture can be fine-tuned for fuel economy
- Coating protects the electrode surfaces from contamination and erosion by combustion residue and particulates
- Made for its specific application and position, with the diagnostic feedback the ECU requires
Quick facts
- Part: Walker Products 250-241207 oxygen sensor
- Fits: 2017-2020 Porsche 718 Boxster H4 2.0L or 2.5L and other vehicles
- Position: Downstream, downstream left, downstream right
- Condition: New
A failing sensor might make the engine run poorly, raise fuel consumption or light the malfunction indicator light. Those signs have several possible causes, so with the engine off and cool, look over the sensor, its wiring harness and the connector for physical damage before replacing anything. If the sensor is the cause, this one replaces it.
Fits
This oxygen sensor is listed for a wide range of Porsche models, led by the 2017-2020 Porsche 718 Boxster H4 2.0L or 2.5L, the 2017-2020 Porsche 718 Cayman H4 2.0L or 2.5L and the 2017-2019 Porsche 911 H6 3.0L. If your Porsche is not one of those, enter its year, model and engine in the "Vehicles it fits" section.

Frequently Asked Questions
Is this the Porsche 911 oxygen sensor for 2017-2019 cars with the H6 3.0L?
Yes. Walker Products 250-241207 is listed for the 2017-2019 Porsche 911 H6 3.0L. The "Vehicles it fits" section shows the other Porsche models it fits.
Does Walker Products 250-241207 come as a single oxygen sensor or a pair?
It is a single sensor. The listing holds one oxygen sensor, and each listed application takes one.
Is this oxygen sensor narrow-band or wideband?
Narrow-band. This sensor has 4 wires, a direct-fit design and an M18 - 1.5 thread.
What can a failing downstream oxygen sensor do to the engine?
A failing sensor might raise exhaust emissions, light the malfunction indicator light, or, on newer cars, store a fault code in the ECU. A shop can read the code to see whether it points to this sensor.
What protects the electrodes on this oxygen sensor?
The electrodes are made of a gas-permeable platinum layer. A coating keeps their surfaces from contamination and erosion by combustion residue and particulates in the exhaust gases.
