Walker Oxygen Sensors are precision made for outstanding performance and manufactured to meet and exceed all original equipment specification and test requirements.

Features and Benefits:

• Improved Engine Response & Performance
• Lower Emissions
• Improved Fuel Economy
• Longer Sensor Life
• Meets OEM Specifications

Installation Notes: Vehicles equipped with Air Fuel Ratio Sensors may look very similar to the Oxygen Sensor. Please confirm the correct part before ordering and if the connector does not match, do not install

Contaminated Sensors Void Manufacturers Warranty.

Oxygen sensors prematurely fail when the sensor’s ceramic element is exposed to certain types of silicone compounds or when an oil-burning engine adds to the sensor becoming oil-fouled. Small amounts of tetra-ethyl lead in the gasoline or over-the-counter fuel additives, which are not “oxygen sensor safe”, can also kill an oxygen sensor and void the manufacturers warranty.

Failures can occur instantaneously at the time the contaminant contacts the oxygen sensor, causing a dead sensor, or gradually over a period of time. Gradual deterioration results in a slow sensor which does not react as quickly as it should, causing the catalytic converter to perform less efficiently. This can lead to premature failure of the catalytic converter.

Oxygen Sensors with these Symptoms Void Manufacturers Warranty Coverage
