NAMZ O2 SENSOR BUNG ADAPTOR & EXTENSION

O2 Bung adapter set & cable extension

Used to reduce exhaust sensor thread from 18mm to 12mm so late H-D models, equipped with 12mm O2 sensors, can be used with earlier 18mm sensor style exhausts. Includes required O2 sensor extension cable for 10-16 Touring models.

Fits: > 10-16 Touring (with pre-2010 exhaust) (NU)
