Direct Fit Oxygen Sensor for Mustang
NTK Direct Fit Oxygen Sensor 22145 is a specific-fit heated oxygen sensor built for downstream applications on select Ford Mustang models. It uses a threaded mounting design and a 4-wire configuration to match the original sensor layout.
Key Features
- Specific-fit oxygen sensor for direct replacement use
- Heated sensor design for faster operating response
- 4-wire construction with threaded mounting
- 18 mm thread diameter and 15.91 in. harness length
- NTK part number 22145
Detailed Description
NTK 22145 is part of the Direct Fit Oxygen Sensor line, engineered to match OE-style fit, form, and function. As an oxygen sensor for Ford Mustang applications, it is built for downstream right and downstream left locations on 2015-2017 models, with notes identifying B1S2 and B2S2 positions where applicable. The heated design and specific-fit construction support accurate replacement of the original sensor without changing the factory mounting style. This part cross-references Monroe Shocks & Struts (e.g., FR3Z9G444C) for the same application.
What It Is Used For
- Replacing a worn or failed downstream oxygen sensor
- Restoring proper sensor signal output for emissions control
- Addressing check engine light concerns related to oxygen sensor faults
- Correcting drivability issues tied to inaccurate exhaust feedback
Installation Notes and Tips
Verify the downstream left or downstream right location before installation. Confirm the 18 mm thread diameter, 4-wire layout, and harness length against the original sensor to ensure proper routing and connection. Use the fitment notes for 2015 Mustang applications, since the listed positions change by bank and build date.
Quality Assurance
NTK is a major original equipment oxygen sensor supplier and tests these sensors during manufacturing to meet or exceed OE specifications. The Direct Fit Oxygen Sensor line is backed by NTK's OE-focused engineering and manufacturing process.
