Walker Products 350-34555 oxygen sensor for the 2000-2003 Porsche Boxster H6 2.7L or 3.2L measures the oxygen content of the exhaust gas to monitor combustion efficiency. It is made for its specific application and fitment position, and it supplies the diagnostic feedback the ECU needs.
- Electrodes made of a gas-permeable platinum layer
- Monitors exhaust gases and helps reduce pollutants
- Measures oxygen levels to fine-tune the air-fuel mixture and support fuel economy
- Coating protects the electrode surfaces from contamination and erosion by combustion residue and particulates
- Narrow-band design with four wires
Quick facts
- Part: Walker Products 350-34555 oxygen sensor
- Fits: 2000-2003 Porsche Boxster H6 2.7L or 3.2L
- Position: Upstream left, upstream right, downstream left, downstream right
- Condition: New
A failing sensor can show up as rough running, higher fuel consumption, higher exhaust emissions or a malfunction indicator light. Those signs can also point elsewhere, so with the engine off and cool, look over the sensor, its wiring harness and the connector for physical damage before you replace the sensor.
Fits
It is a direct-fit oxygen sensor replacement for the 2000-2003 Porsche Boxster with the H6 2.7L or 3.2L engine. This listing is one sensor, and each of the upstream and downstream positions on the left and right takes one.

Frequently Asked Questions
Is this an oxygen sensor for the 2000-2003 Porsche Boxster H6 3.2L?
Yes. Walker Products 350-34555 fits the 2000-2003 Porsche Boxster with the H6 2.7L or 3.2L engine.
What type of oxygen sensor is Walker Products 350-34555?
It is a narrow-band sensor with four wires and an M18 - 1.5 thread.
Which sensor positions does this oxygen sensor cover?
Walker Products lists 350-34555 for the upstream left, upstream right, downstream left and downstream right positions. Each position takes one sensor.
Could a bad oxygen sensor make my engine run poorly or light the check engine lamp?
Yes, it can. A failed sensor can cause rough running, higher fuel consumption, higher exhaust emissions or a lit malfunction indicator light.
What does the coating on this oxygen sensor protect against?
The coating keeps combustion residue and particulates in the exhaust from contaminating or eroding the electrode surfaces, which are made of a gas-permeable platinum layer.
