Used to reduce the oxygen sensor thread from 18 mm to 12 mm, allowing later HD models equipped with 12 mm O2 sensors to be compatible with earlier model exhausts with 18 mm sensors.

The active intake and exhaust system eliminator kit is used to avoid logging a diagnostic trouble code when installing some aftermarket air filters and exhaust systems that require the removal of active systems.

Precision manufactured with a ceramic body made of stabilized zirconium dioxide, surface coated with gas-permeable platinum electrodes and a porous ceramic to help prevent erosion due to contamination and particulates in the exhaust gases
