Walker Products 350-35008 oxygen sensor for the 1999-2004 Volkswagen Jetta V6 2.8L, the 2001-2005 Jetta 4-cylinder 1.8L and other vehicles measures the oxygen in the exhaust gas to show how well the engine burns fuel. This Walker Products oxygen sensor is a 5-W wide-band unit, made for its specific application and fitting position.
- Measures oxygen levels to help fine-tune the air-fuel mixture and fuel economy
- Coating protects the electrode surfaces from contamination and erosion by combustion residue and particulates
- Monitors exhaust gases to help reduce pollutants
- Electrodes with a gas-permeable platinum layer
Quick facts
- Part: Walker Products 350-35008 oxygen sensor
- Fits: the 1999-2004 Volkswagen Jetta V6 2.8L, the 2001-2005 Jetta 4-cylinder 1.8L and other vehicles
- Position: Upstream, upstream left, upstream right, upstream rear
- Condition: New
A failing sensor can show up as rough running, higher fuel use, more exhaust emissions or a lit malfunction indicator light. Before you replace this sensor, look over its wiring harness and connector for physical damage and rule out other faults that give similar symptoms.
Fits
The 1999-2005 Volkswagen Golf V6 2.8L, the 2001-2006 Golf 4-cylinder 1.8L and the 2002-2004 Volkswagen Passat W8 4.0L take this oxygen sensor too, along with many other vehicles. This listing is one sensor, whether it goes on as an O2 sensor for the 2001-2005 VW Jetta 4-cylinder 1.8L or on another fitting car, and each upstream position on the engine takes one. Owners of any other car can find their year and engine in the "Vehicles it fits" section.

Frequently Asked Questions
Is this the right oxygen sensor for a 1999-2004 VW Jetta V6 2.8L?
Yes. Walker Products 350-35008 fits the 1999-2004 Volkswagen Jetta V6 2.8L, and the 2001-2005 Jetta 4-cylinder 1.8L takes it too.
Does this VW Golf oxygen sensor fit a 2001-2006 Golf 4-cylinder 1.8L?
Yes. Walker Products 350-35008 fits the 2001-2006 Volkswagen Golf 4-cylinder 1.8L, and the 1999-2005 Golf V6 2.8L takes it as well.
What thread size does this wide-band oxygen sensor have?
This oxygen sensor has an M18 - 1.5 thread. It is a 5-W Wide-Band type.
Can a bad oxygen sensor make my engine run poorly?
It can, along with higher fuel use, more exhaust emissions or a lit malfunction indicator light. Other faults can cause these too, so a shop can read the stored fault codes.
What protects the electrodes on this oxygen sensor from exhaust residue?
A coating over the electrode surfaces guards against contamination and erosion from combustion residue and particulates. The electrodes carry a gas-permeable platinum layer.
