NTK 22051 Oxygen Sensor - Downstream Left or Downstream Right
Direct Fit Oxygen Sensor for Ford Applications
NTK 22051 is a direct fit heated oxygen sensor built for specific downstream positions on select Ford vehicles. It is engineered for accurate exhaust feedback, OE-style fitment, and dependable signal performance in emissions control systems.
Key Features
- Heated oxygen sensor with 4-wire design
- Specific fit for direct replacement installation
- Threaded mounting type with 18.000 mm thread diameter
- 16.0 wiring harness length
- Built for downstream right and downstream left locations
- NTK 22051 direct fit replacement for OE-style service
Product Details
NTK Direct Fit Oxygen Sensor 22051 is part of the NTK sensor line, a product family focused on OE application coverage for import and domestic vehicles. NTK controls ceramic sensor production from raw material through finished component, supporting consistent sensor construction and application-specific fit. This oxygen sensor is designed for 2015-2020 Ford Mustang downstream right and downstream left positions, and 2015-2017 Ford F-150 downstream right and downstream left positions. It also cross-references DENSO Auto Parts 234-4968 for the same application.
For buyers searching for a 2015-2020 Ford Mustang downstream oxygen sensor or a 2015-2017 Ford F-150 downstream oxygen sensor, NTK 22051 provides a direct-fit replacement option with the correct threaded mounting and harness configuration. The part number 22051 is also a useful reference when matching OE-style emissions components for Ford Mustang and Ford F-150 service work.
Common Issues This Part Can Address
- Check engine light related to downstream oxygen sensor performance
- Faulty exhaust gas feedback affecting emissions monitoring
- Incorrect sensor response in the downstream right or left location
- Replacement need after sensor aging, contamination, or wiring wear
- Restoration of OE-style sensor fitment on Ford Mustang and Ford F-150 applications
Installation Notes and Tips
Confirm the vehicle year, model, and sensor position before ordering. This sensor is specific fit and is intended for threaded installation in the listed downstream locations. Verify harness routing, connector match, and exhaust thread condition during replacement. Use the application notes for your exact Ford Mustang or Ford F-150 configuration, since fitment varies by model year and position.
Quality Assurance
NTK manufactures oxygen sensors to meet or exceed OE specifications and tests them during production for quality and reliability. As part of the NGK family of products, NTK supports OE application coverage with sensor technology developed for modern emissions systems.
