Walker Products 350-34259 oxygen sensor for the 1999-2000 Chevrolet Silverado 2500 V8 6.0L and other vehicles measures the oxygen in the exhaust gas. This narrow-band, 4-wire Walker Products oxygen sensor is 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 gas
- Determines the oxygen content of the exhaust gas and monitors the air-fuel ratio for combustion efficiency
- Oxygen readings help fine-tune the air-fuel mixture to support fuel economy
- Electrodes made of a gas-permeable platinum layer
- Monitors exhaust gases to help reduce pollutants
Quick facts
- Part: Walker Products 350-34259 oxygen sensor
- Fits: 1999-2000 Chevrolet Silverado 2500 V8 6.0L and other vehicles
- Position: Upstream, upstream left, upstream right
- Condition: New
A failing sensor might show up as a rough-running engine, higher fuel use, more exhaust emissions or a lit malfunction indicator light. A damaged wiring harness or connector can also sit behind those signs, so look both over for physical damage with the engine off and cool, and trace the cause before buying a sensor. The fitment lists a quantity of one, so this listing is a single sensor.
Fits
Besides the 1999-2000 Chevrolet Silverado 2500 V8 6.0L, this direct-fit sensor is made for the 1996-1999 Chevrolet C1500 V8 5.0L or 5.7L and the 1996-1999 Chevrolet K1500 V8 5.0L or 5.7L, along with other Chevrolet and GMC models.

Frequently Asked Questions
Is the Walker Products 350-34259 right for a 1999-2000 Chevrolet Silverado 2500 V8 6.0L?
Yes. Walker Products 350-34259 is listed for the 1999-2000 Chevrolet Silverado 2500 V8 6.0L, and it also fits the 1996-1999 Chevrolet C1500 V8 5.0L or 5.7L.
Is this oxygen sensor narrow-band or wideband?
Narrow-band. Walker Products 350-34259 is a 4-wire narrow-band sensor with an M18 - 1.5 thread.
What protects the electrodes on this oxygen sensor?
A coating protects the electrode surfaces from contamination and erosion by combustion residue and particulates in the exhaust gas. The electrodes are made of a gas-permeable platinum layer.
What can a failing upstream oxygen sensor cause?
A failing sensor might lead to rough running, higher fuel consumption, more exhaust emissions or a lit malfunction indicator light. A shop can read stored fault codes to see whether the sensor is involved.
Does Walker Products 350-34259 replace CTK-OSGM4018?
Yes. CTK-OSGM4018 is listed as an interchange number for this sensor.
