Extensions go bad or get damaged while installing your long tube headers? Or maybe just looking to save time on the install? UPR has you covered. These 24" long front O2 sensor extensions fit the 2011-2014 model Mustang 3.7L V6 Cyclone and work flawlessly with long tube headers. Most aftermarket longtubes relocate the front O2 sensors further away so the stock wiring does not fit. These extensions are a simple solution that keeps you from having to cut and lengthen your factory wiring.
