What is this O2 extension harness used for?

This O2 extension harness is designed to extend the reach of your oxygen sensor wiring when installing long tube headers. Long tube headers often require the O2 sensors to be relocated further downstream, requiring longer wiring to reach the sensor.

Is this O2 extension harness sold individually or as a pair?

This Kooks O2 extension harness is sold individually. Depending on your application, you may need to purchase two harnesses.

Is this O2 extension harness compatible with other brands of headers?

While this O2 extension harness is designed for use with Kooks headers, it may be compatible with other brands that use the same 4-pin round connector. Check the connector type and wiring configuration to ensure compatibility.
