These 24" long rear O2 sensor extensions fit 2011-2017 Mustang GT 5.0L Coyote and 3.7L V6 and work great on cars with longtubes. Most aftermarket longtubes relocate the O2 sensors further away so the stock wiring does not fit. These extensions keep you from having to cut and lengthen your factory wiring.
