The Kooks Headers CAS-105067 O2 Extension Kit is designed for Chrysler 5.7L, 6.1L, and 6.4L HEMI engines requiring extended oxygen sensor wiring when installing aftermarket headers. This kit includes two 6-inch front extension harnesses and two 18-inch rear extension harnesses, all equipped with 4-pin connectors for proper sensor connectivity. Oxygen sensor extensions are typically included with Kooks header kits when required, but this kit is available as a direct replacement if the original harnesses become damaged or lost. Built to maintain proper sensor function and reliable connections, this extension kit ensures accurate readings and optimal engine performance after header installation.
