Are these extensions vehicle-specific?

Yes, these Kooks O2 sensor extensions are specifically designed for the 2015 and newer Ford Mustang GT when installing long tube headers. They ensure proper O2 sensor placement and function after the header installation.

Do these extensions require any modifications to install?

No, these O2 sensor extensions are designed for direct fitment. They plug directly into the factory O2 sensor harness without any cutting or splicing, making installation straightforward.

What is the purpose of using O2 sensor extensions?

When installing long tube headers, the O2 sensor bungs are often relocated further downstream. The factory O2 sensor wiring may not be long enough to reach the new location, and these extensions provide the necessary length to connect the sensors properly.
