This part cross-references Bosch 18050 and Gates 18149 for the same application.

What It Helps Address

• Check engine light related to oxygen sensor performance
• Incorrect air-fuel ratio feedback from a worn downstream sensor
• Emissions test failures tied to sensor response issues
• Rough or inconsistent exhaust monitoring data in the catalyst monitoring circuit
• Replacement needs after sensor aging, contamination, or electrical failure

Installation Notes and Tips

Verify the vehicle year, make, model, and sensor position before installation. Match the 4-wire connector, threaded mount, and harness length to the original sensor, and inspect the exhaust bung threads and connector condition before fitting. For best results, compare the removed sensor to NTK 24461 before final installation.
