NTK 22537 Oxygen Sensor - Downstream, Downstream Left or Downstream Right

Direct Fit Oxygen Sensor for Ford and Lincoln

NTK Oxygen Sensor 22537 is a direct fit, heated oxygen sensor built for specific applications with threaded mounting and OE-style form. It is engineered for downstream use on select Ford Super Duty trucks, Expedition, and Lincoln Navigator models.

NTK 22537 uses a 4-wire design with a 15.7500-inch harness length and an 18.000 thread diameter. The specific-fit design helps maintain the original sensor layout and connection style for a clean replacement on compatible Ford F-250 Super Duty, F-350 Super Duty, F-450 Super Duty, F-550 Super Duty, Expedition, and Lincoln Navigator applications.

Key Features

• Direct fit oxygen sensor for specific applications
• Heated sensor design for downstream exhaust monitoring
• Threaded mounting with 18.000 thread diameter
• 4-wire configuration with 15.7500-inch wiring harness length
• OE-style fit, form, and function from NTK

Detailed Description

NTK 22537 is part of the Direct Fit Oxygen Sensor line, which focuses on application-specific replacement sensors rather than universal parts. NTK draws on its OE sensor manufacturing background and ceramic technology to produce sensors with consistent fit and reliable signal performance. This part cross-references Bosch 18070 and DENSO Auto Parts 234-4576 for the same application.

What It Helps Address

• Faulty downstream oxygen sensor readings
• Check engine light concerns related to exhaust monitoring
• Incorrect air-fuel feedback from a worn sensor
• Connector and harness mismatch from a non-specific replacement
• Fitment issues on application-specific exhaust sensor locations

Installation Notes and Tips

Use the threaded mounting style and harness length to confirm routing before installation. Verify the vehicle application, downstream position, and connector match before replacing the sensor. For best results, compare the original sensor layout to the OE-style configuration of NTK 22537.

Quality Assurance

NTK states that its oxygen sensors are extensively tested during manufacturing to meet or exceed OE specifications. As part of the NGK family of products, NTK supports import and domestic applications with OE-level sensor coverage and manufacturing control from raw material to finished product.
