NTK 22507 Oxygen Sensor - Downstream

Direct-Fit Oxygen Sensor

NTK Oxygen Sensor 22507 is a direct-fit, heated replacement built for specific applications with threaded mounting and a 4-wire design. It is engineered for accurate exhaust monitoring and reliable signal response in import and domestic vehicles.

• Heated oxygen sensor for faster operating response.
• Specific-fit design for straightforward replacement.
• Threaded mounting with 18 mm thread diameter.
• 22-inch wiring harness length for application-specific routing.
• NTK 22507 is tested during manufacturing for quality and reliability.

Detailed Application Coverage

Fits 1996 Ford Escort, downstream. Fits 1996 Mercury Tracer, downstream. This part cross-references BBB Industries 13578 for the same application. As part of NTK Direct Fit Oxygen Sensor line, it reflects the brand's focus on streamlined coverage and OE-style fit, form, and function. The NTK 22507 is a practical choice for restoring proper oxygen sensor performance on the Ford Escort and Mercury Tracer when the original downstream sensor needs replacement.

Common Issues It Can Address

• Check engine light related to oxygen sensor performance.
• Incorrect air-fuel ratio feedback from a worn sensor.
• Slow sensor response during closed-loop operation.
• Fault codes tied to downstream exhaust monitoring.

Installation Notes and Tips

Confirm the downstream location, connector style, thread size, and harness length before installation. Use the vehicle's original routing path to avoid strain on the lead wire and verify the threaded sensor seats correctly in the exhaust bung.

Quality Assurance

NTK states that these oxygen sensors are extensively tested during manufacturing and built to meet or exceed OE specifications. The brand is part of the NGK family and is recognized as a major original equipment oxygen sensor supplier.
