What is an O2 extension harness?

An O2 extension harness extends the factory oxygen sensor wires. This is often needed when installing long tube headers, as the new header location may require the O2 sensor to be relocated further away from the factory wiring harness.

Is this harness CARB compliant?

This O2 extension harness does not affect emissions, as it only extends the factory wiring. Check your local and state laws regarding header modifications.

What other parts are needed for a header install?

Besides the headers themselves, you may need new gaskets and header bolts. Refer to the header manufacturer's instructions for a complete list of required parts and recommended installation procedures.
