Walker Products 250-241089 oxygen sensor for the 2022-2026 Porsche 911 H6 3.0L and other vehicles measures the oxygen in the exhaust gas. This 4-wire, narrow-band sensor is a direct fit, made for its specific application and fitment position.
- Determines the oxygen content of the exhaust gas to monitor the air-fuel ratio for combustion efficiency
- Coating protects the electrode surfaces from contamination and erosion by combustion residue and particulates
- Electrodes made of a gas-permeable platinum layer
- Monitors exhaust gases to help reduce pollutants
- Measures oxygen levels to help fine-tune the air-fuel mixture and improve fuel economy
Quick facts
- Part: Walker Products 250-241089 oxygen sensor
- Fits: 2022-2026 Porsche 911 H6 3.0L and other vehicles
- Position: Downstream, upstream left, upstream right, downstream left, downstream right, downstream front, downstream rear
- Condition: New
A failing sensor can make the engine run poorly, raise fuel consumption or exhaust emissions, or turn on the malfunction indicator light. These symptoms alone do not prove the sensor is at fault; a damaged harness or connector is another possibility.
Fits
The 2022-2026 Porsche 911 H6 3.0L, the 2017-2019 Audi Q7 V6 3.0L and the 2015-2018 Audi A8 Quattro V6 3.0L are among the vehicles this sensor fits, along with many others. This listing is one sensor, and each application takes one at the position it serves.

Frequently Asked Questions
Is this the right Audi Q7 oxygen sensor for a 2017-2019 model with the V6 3.0L?
Yes. Walker Products 250-241089 fits the 2017-2019 Audi Q7 V6 3.0L. If your car is a different one, look up your year, model and engine in the "Vehicles it fits" section.
Is this a Porsche 911 oxygen sensor for the 2022-2026 model with the H6 3.0L?
Yes. This sensor fits the 2022-2026 Porsche 911 H6 3.0L, and that application takes one sensor.
Is Walker Products 250-241089 a narrow-band sensor?
Yes. Walker Products 250-241089 is a 4-wire narrow-band oxygen sensor with an M18 - 1.5 thread.
What happens to the engine when this oxygen sensor wears out?
The engine can run poorly, fuel consumption or exhaust emissions can rise, or the malfunction indicator light can come on. Newer vehicles may also store fault codes in the ECU.
Is this an upstream or a downstream oxygen sensor?
It depends on the application. Upstream left and right and downstream positions (left, right, front, rear) are listed, and each part number is made for its specific application and fitment position.
