Walker Products 350-34564 oxygen sensor for the 2006-2008 Porsche 911 H6 3.8L and the 2006-2009 911 H6 3.6L measures the oxygen content of the exhaust gas so the ECU can monitor combustion efficiency. This is a downstream sensor, made for its specific application and fitment position.
- Coating protects the electrode surfaces from contamination and erosion by combustion residue and particulates in the exhaust gases
- Gas-permeable platinum layer on the electrodes
- Narrow-band sensor that reports oxygen levels to help fine-tune the air-fuel mixture and support fuel economy
- Monitors exhaust gases to help reduce pollutants
Quick facts
- Part: Walker Products 350-34564 oxygen sensor
- Fits: 2006-2008 Porsche 911 H6 3.8L and the 2006-2009 911 H6 3.6L
- Position: Downstream left, downstream right, downstream front, downstream rear
- Condition: New
A failing oxygen sensor can show up as poor engine running, higher fuel use, more exhaust emissions or a lit malfunction indicator light. Before you replace it, rule out physical damage to the sensor, its wiring harness and the connector, along with other faults that give the same signs.
Fits
This sensor fits the 2006-2009 and 2011 Porsche 911 H6-3.6L, the 2006-2008 and 2014-2016 911 H6-3.8L, and the 2016 and 2018-2019 911 H6-4.0L. This listing is one sensor, and each of these engines takes one.

Frequently Asked Questions
Does this Porsche 911 oxygen sensor fit the 2014-2016 911 H6-3.8L?
Yes. Walker Products 350-34564 fits the 2014-2016 Porsche 911 H6-3.8L, and this listing is one sensor for the downstream position.
Is this Walker Products oxygen sensor narrow-band or wideband?
Walker Products 350-34564 is a narrow-band oxygen sensor with an M18 - 1.5 thread.
Is this a downstream or upstream oxygen sensor?
Downstream. This sensor is listed for the downstream left, downstream right, downstream front and downstream rear positions.
What can a failing oxygen sensor look like on the road?
Poor engine running, higher fuel use, more exhaust emissions or a lit malfunction indicator light can all be signs of a failing sensor. Other faults can cause them too.
What does the coating on this oxygen sensor do?
The coating keeps combustion residue and particulates in the exhaust gases from contaminating and eroding the electrode surfaces. The electrodes are made of a gas-permeable platinum layer.
