NTK 22541 Oxygen Sensor - Downstream, Downstream Left or Downstream Right

Direct Fit Oxygen Sensor

The NTK 22541 is a specific-fit heated oxygen sensor built for downstream applications across select Ford trucks, vans, and cars. It uses a threaded mounting design and a 4-wire configuration for OE-style replacement on covered applications.

Key Features

• Direct Fit Oxygen Sensor line from NTK for specific applications
• Heated sensor design for faster operating response
• 4-wire construction with threaded mounting
• 18 mm thread diameter and 21.75 in. harness length
• OE-equivalent design for covered Ford applications

Detailed Description

NTK 22541 is part of the Direct Fit Oxygen Sensor line and is engineered for exact-application replacement where a specific downstream sensor is required. Fitment includes 2014-2016 Ford Fusion, 2015-2017 Ford F-150, 2015-2017 Ford Mustang, 2016 Ford Edge, and 2016-2019 Ford Transit-150, Transit-250, Transit-350, and Transit-350 HD, along with 2020-2022 Ford F-250 Super Duty and F-350 Super Duty coverage. This part cross-references Ford service numbers DS7Z9G444A and FL3Z9G444C for the same application.

NTK is known for oxygen sensor manufacturing and OE-level application coverage. The 22541 follows that approach with a heated, threaded design intended to match original equipment fit, form, and function on the listed Ford applications. The part number 22541 is used for direct replacement identification, and NTK 22541 is supported by manufacturing testing aimed at consistent quality and reliability.

What It Is Used For

• Replacing a failed downstream oxygen sensor
• Restoring proper air-fuel feedback to the engine control system
• Addressing check engine light concerns related to sensor performance
• Correcting drivability issues caused by inaccurate exhaust oxygen readings
• Replacing a sensor with damaged wiring, connector, or threaded mount

Installation Notes and Tips

Verify the exact position and notes in the fitment list before ordering, since this application includes multiple downstream locations and OE-specific placements. Confirm connector style, thread size, and harness length against the original sensor before installation. Use the vehicle service information for proper removal and installation procedures.

Quality Assurance

NTK states that its oxygen sensors are extensively tested during manufacturing and built to meet or exceed OE specifications. The part number 22541 is part of NTK's direct-fit oxygen sensor program for application-specific replacement.
