Oxygen Sensor for 2018-2025 Alfa Romeo Stelvio & More - Walker 350-34156

Walker Products 350-34156 oxygen sensor for the 2018-2025 Alfa Romeo Stelvio 4-cylinder 2.0L and other vehicles measures the oxygen in the exhaust gas from the downstream position. This narrow-band, 4-wire direct-fit sensor uses that reading to show how efficiently combustion is running.

• Electrodes made of a gas-permeable platinum layer
• Coating that protects the electrode surfaces from contamination and erosion by combustion residue and particulates in the exhaust gases
• Air-fuel ratio monitoring that tracks combustion efficiency
• Oxygen level readings that help fine-tune the air-fuel mixture and support fuel economy
• Exhaust gas monitoring that helps reduce pollutants

Quick facts

• Part: Walker Products 350-34156 oxygen sensor
• Fits: 2018-2025 Alfa Romeo Stelvio 4-cylinder 2.0L and other vehicles
• Position: Downstream
• Condition: New

A failing sensor can show up as an engine that runs poorly, higher fuel consumption, more exhaust emissions or a lit malfunction indicator light. These signs alone do not prove the sensor is at fault, since a vacuum leak can also make an engine run poorly. With the engine off and cool, the sensor, wiring harness and connector can be looked over for physical damage.

Fits

This is a direct-fit replacement for the 2018-2025 Alfa Romeo Stelvio 4-cylinder 2.0L, the 2017-2023 Alfa Romeo Giulia 4-cylinder 2.0L and the 2012-2019 Fiat 500 4-cylinder 1.4L.
