Replace the O2 extension your exhaust needs
Get your sensor wiring connected again with the correct Kooks replacement extension for your listed Camaro, Firebird or GM truck / SUV application. CAS-109007 supplies one 24-inch front harness with a 4-pin connector, for replacing a damaged or lost extension.
SKU: CAS-109007
The correct harness for the job
One 24-inch front harness; 4-pin. Match the plug type, sensor position and extension length to the part you are replacing. Front and rear extensions do different jobs, so use the listed contents rather than choosing by vehicle name alone.

What is supplied?
One 24-inch front harness; 4-pin.
Do I need this as an extra with a new header kit?

Will this change how my O2 sensor works?
It extends the electrical connection. Match the existing sensor and harness connector; the extension is not a replacement oxygen sensor.
