Walker Products 350-64072 Oxygen Sensor, Original Equipment Replacement O2 Sensor, Air Fuel Ratio

Description

Product Overview

The Walker Products 350-64072 oxygen sensor is engineered as a direct replacement for original equipment specifications. Constructed from high‑grade ceramic, the sensor provides stable and accurate detection of oxygen levels in the exhaust stream, enabling the engine control unit to maintain the ideal air‑fuel mixture. Its flange‑mount design simplifies installation on a wide range of vehicle makes and models, while the push‑pull output type ensures reliable signal transmission under harsh operating conditions. The sensor measures 2.15 x 1.95 x 5.85 inches and weighs just 3.38 ounces, making it compact enough for tight engine bays without sacrificing durability.

Usage

This oxygen sensor is intended for use in gasoline‑powered passenger cars, light trucks, and SUVs that require precise air‑fuel ratio control. It is ideal for vehicles equipped with electronic fuel injection systems where emissions compliance and fuel efficiency are critical. The sensor can be installed during routine maintenance, after a failed OEM sensor, or as part of a performance upgrade package. Its robust ceramic construction tolerates temperature extremes from -40°F to 1500°F, making it suitable for both cold‑climate starts and high‑load highway driving. Whether you are a professional mechanic or a DIY enthusiast, the sensor’s straightforward flange mounting reduces installation time and minimizes the risk of misalignment.

FAQ

What vehicles are compatible with the 350‑64072 sensor?

The sensor fits any vehicle that originally uses the OEM part numbers 15380, 25679, 234‑9083, 213‑4747, or 11902. This includes many makes from American, European, and Asian manufacturers. Consult the vehicle’s service manual or contact Walker support for a specific fit list.

How does the ceramic element improve performance?

Ceramic sensors respond more quickly to changes in exhaust oxygen levels, allowing the engine control unit to adjust fuel delivery faster. This results in smoother idle, better throttle response, and reduced emissions.

Can I install the sensor myself?

Yes. The flange‑mount design requires only basic hand tools. Disconnect the battery, remove the old sensor, and bolt the new Walker sensor in place. Be sure to use anti‑seize compound on the threads and verify the sensor’s orientation before tightening.

What warranty does Walker Products offer?

Walker Products provides a limited warranty that covers defects in materials and workmanship for a period of one year from the date of purchase. The warranty also includes access to technical support for installation questions.

Will this sensor affect my vehicle’s emissions test?

Because the sensor meets OEM specifications, it will help your vehicle pass emissions testing by maintaining the correct air‑fuel ratio. Proper installation and regular maintenance are essential for optimal performance.
