Ford Mustang Extension Harness - Kooks Headers - 12in - O2 Ext Harn - '05-'10. This 12-inch oxygen sensor extension harness uses a round 4-pin connector to reach relocated O2 sensors when installing headers.

Use it as a direct plug-in replacement for a damaged or lost extension, or when your header setup needs extra reach. It works with 2005-2010 Mustang applications that use the Ford round 4-pin O2 connector—commonly 2005-2010 4.6L 3V GT and 2007-2010 GT500. Kooks header kits include extensions where required; this part suits replacements or specific builds. For Kooks p/n 11312000 or 11312200 on a 2005-2010 4.6L 3V GT with automatic, two are needed; none are needed for p/n 11312010.
