Walker Products 350-33092 oxygen sensor for the 1983-1984 Porsche 928 V8 4.7L, the 1985-1987 928 V8 5.0L and other vehicles senses the oxygen left in the exhaust gas. This upstream, 3-wire narrow-band sensor is a direct-fit replacement.
- Made for its specific application and fitment position, with the diagnostic feedback the ECU needs
- Monitors the air-fuel ratio for combustion efficiency from the oxygen content of the exhaust
- Oxygen readings help fine-tune the air-fuel mixture and support fuel economy
- Coating protects the electrode surfaces from contamination and erosion by combustion residue and particulates
- Electrodes with a gas-permeable platinum layer
- Monitors exhaust gases to help reduce pollutants
Quick facts
- Part: Walker Products 350-33092 oxygen sensor
- Fits: 1983-1984 Porsche 928 V8 4.7L, the 1985-1987 928 V8 5.0L and other vehicles
- Position: Upstream
- Condition: New
A failing sensor can make the engine run poorly, use more fuel or light the malfunction indicator light. These signs alone do not prove the sensor is at fault, since an exhaust leak near it can look much the same. With the engine off and cool, the sensor, wiring harness and connector can be checked for physical damage.

Frequently Asked Questions
Is this the Porsche 928 oxygen sensor for both the 1983-1984 V8 4.7L and the 1985-1987 V8 5.0L?
Yes. Walker Products 350-33092 fits the 1983-1984 Porsche 928 V8 4.7L and the 1985-1987 Porsche 928 V8 5.0L, with one sensor per car.
Is this a Porsche 911 oxygen sensor for the 1984-1985 H6 3.2L?
Yes. Walker Products 350-33092 fits the 1984-1985 Porsche 911 H6 3.2L as an upstream sensor, and that engine takes one.
How many wires does this Walker Products oxygen sensor have?
Walker Products 350-33092 is a 3-wire, narrow-band, direct-fit sensor with an M18 - 1.5 thread.
What can a failing upstream oxygen sensor cause?
A failing sensor can make the engine run poorly, raise fuel consumption or turn on the malfunction indicator light. Newer cars may also store fault codes.
What is the coating on this oxygen sensor's electrodes for?
The coating keeps combustion residue and exhaust particulates from contaminating or eroding the electrode surfaces. The electrodes use a gas-permeable platinum layer.
