The correct front-sensor extension for your earlier Mustang
The Kooks CAS-105979 supplies one 8" six-pin front O2 extension for the listed 2015-2017 Mustang application. Choose the year group and connector specification together when replacing the lead on a matched header installation.
SKU: CAS-105979
The year group changes the connector
This is the six-pin 2015-2017 version. The 2018+ Mustang front extension has a different five-pin specification. Match the actual connector, then route the lead clear of the hot exhaust.
One lead for the listed position
The listing supplies one front extension, not a pair or a complete front-and-rear set. Relevant Kooks header kits already include extensions where needed.
