Description

Used in custom applications to reduce exhaust sensor thread from 18mm x 1.50 to 12mm x 1.25 so late H-D models, equipped with 12mm oxygen sensors, can be used with earlier 18mm sensor style exhaust systems.
Note: For 10-16 Touring models an extra extension cable is required, which is available as 578303 bung set & cable extension kit.
