Walker Products 350-34525 oxygen sensor for the 1996-1999 Chevrolet Silverado V8 5.7L and other vehicles measures the oxygen in the exhaust gas to track combustion efficiency. This Walker Products oxygen sensor is a 4-wire, direct-fit narrow-band unit that gives the ECU the diagnostic feedback it expects.
- Coating protects the electrode surfaces from contamination and erosion by combustion residue and particulates in the exhaust gases
- Monitors exhaust gases to help reduce pollutants
- Determines the oxygen content of the exhaust gas and monitors the air-fuel ratio for combustion efficiency
- Electrodes made of a gas-permeable platinum layer
- Measures oxygen levels so the air-fuel mixture can be fine-tuned for fuel economy
Quick facts
- Part: Walker Products 350-34525 oxygen sensor
- Fits: 1996-1999 Chevrolet Silverado V8 5.7L and other vehicles
- Position: Upstream or downstream (left, right, front or rear by application)
- Condition: New
A failing sensor can make the engine run poorly, raise fuel consumption and exhaust emissions, or turn on the malfunction indicator light. A damaged wiring harness or connector can be behind the same signs, so look those over and find the cause before you buy a sensor.
