Walker Products 350-34105 oxygen sensor for the 2004-2006 Mitsubishi Lancer 4-cylinder 2.4L and other vehicles reads the oxygen content of the exhaust gas to show how efficiently the engine burns fuel. Each part number is made for its specific application and fitting position, and the sensor sends the ECU the diagnostic feedback it requires.
- Coating protects the electrode surfaces from contamination and erosion by combustion residue and particulates
- Electrodes made of a gas-permeable platinum layer
- Oxygen readings help fine-tune the air-fuel mixture for fuel economy
- Monitors exhaust gases to help reduce pollutants
Quick facts
- Part: Walker Products 350-34105 oxygen sensor
- Fits: 2004-2006 Mitsubishi Lancer 4-cylinder 2.4L and other vehicles
- Position: Upstream, downstream
- Condition: New
Rough running, higher fuel use, more exhaust emissions or a lit malfunction indicator light can mean the sensor is worn, but a damaged wiring harness or connector can be behind them too, so look both over for physical damage before replacing the sensor.
Fits

Frequently Asked Questions
Does this Lancer oxygen sensor fit the 2004-2006 Mitsubishi Lancer 4-cylinder 2.4L?
Yes. Walker Products 350-34105 is a direct-fit oxygen sensor for the 2004-2006 Mitsubishi Lancer 4-cylinder 2.4L, and that engine takes one.
Is this sensor the right one for the 1994-1998 Mitsubishi Galant 4-cylinder 2.4L?
Yes. This oxygen sensor fits the 1994-1998 Mitsubishi Galant 4-cylinder 2.4L, which takes one.
Is this Walker Products oxygen sensor narrow-band?
Yes. Walker Products 350-34105 is a 4-wire, narrow-band oxygen sensor with an M18 - 1.5 thread.
What can a worn narrow-band oxygen sensor cause?
A worn sensor can lead to the engine running poorly, higher fuel use, more exhaust emissions or a lit malfunction indicator light. Newer vehicles may also store a fault code in the ECU.
What does the coating on this oxygen sensor protect against?
The coating protects the electrode surfaces from contamination and erosion by combustion residue and particulates in the exhaust gases. The electrodes are made of a gas-permeable platinum layer.
