• Specific-fit design for direct application matching
• Upstream position for Bank 1 Sensor 1 service needs
• 4-wire configuration with female connector
• Threaded mounting with 18.0 mm thread diameter
• Wiring harness length: 13.31 in.; overall length: 16.85 in.
• Radiused polygon connector shape for vehicle-specific fitment

Product Details

Walker Products Aftermarket focuses on engine management and oxygen/air-fuel sensors built for OE replacement use across many vehicle platforms. Part number 350-64041 is matched to the application, mounting position, and connector style required for select Suzuki Grand Vitara and Suzuki SX4 upstream oxygen sensor service. For drivers searching for a 2014-2017 Suzuki Grand Vitara upstream oxygen sensor or a 2007-2009 Suzuki SX4 Bank 1 Sensor 1 replacement, this sensor provides the correct fitment profile for the intended location. Walker Products 350-64041 is also referenced for 2009-2013 Suzuki Grand Vitara upstream service and 2007-2009 Suzuki SX4 front oxygen sensor applications.

This part cross-references no listed aftermarket part numbers in the provided data.

What It Helps Address

• Check engine light related to oxygen sensor performance
• Poor engine operation caused by incorrect air-fuel feedback
• Increased fuel consumption from inaccurate sensor readings
• Higher exhaust emissions from a failing upstream sensor
• Fault codes stored in the ECU for sensor-related issues

Installation Notes and Tips

Confirm the vehicle’s upstream location before installation, especially on Suzuki Grand Vitara and Suzuki SX4 models. Inspect the sensor wiring harness and connector for heat damage, abrasion, or corrosion before replacement. Because this is a threaded, specific-fit sensor, verify thread diameter and connector shape against the original part to ensure proper installation.

Quality Assurance

Walker Products manufactures engine management sensors as OE replacement components and operates as an Automotive ISO9001/TS 16949 certified company. Since 1946, the brand has supplied oxygen and air-fuel sensors for vehicle-specific applications, including upstream service on Suzuki Grand Vitara and Suzuki SX4 platforms.
