Is this harness CARB-approved?

No, this oxygen sensor extension harness is not CARB-approved. That means it cannot be installed on emissions-controlled vehicles in California.

What is this harness used for?

When you install long tube headers, the oxygen sensor bungs are often moved further downstream. This extension harness provides the extra length needed to connect the factory O2 sensor to the relocated bung.

Does this come with one or two harnesses?

This Kooks part number is for a single oxygen sensor extension harness. Most vehicles will require two harnesses when installing long tube headers.
