Walker Products 350-341057 oxygen sensor for the 2017-2020 Porsche 718 Boxster H4 2.0L or 2.5L and other vehicles measures the oxygen content of the exhaust gas. It works downstream in the exhaust and gives the engine computer the feedback it needs to monitor combustion efficiency.

• Monitors exhaust gases to help reduce pollutants
• Oxygen readings help fine-tune the air-fuel mixture to support normal fuel economy
• Coating protects the electrode surfaces from contamination and erosion by combustion residue and particulates in the exhaust gas
• Electrodes made of a gas-permeable platinum layer

A failing sensor can show up as an engine that runs poorly, higher fuel consumption or a lit malfunction indicator lamp. Before you replace the sensor, rule out physical damage to its wiring harness and connector, and read any stored fault codes, because other faults can also set that lamp.
