Namz O2 Sensor Bung Adapter and Extension for Harley-Davidson
40.15 €
Used to reduce the exhaust sensor thread from 18mm to 12mm, so late HD models, fitted with 12mm O2 sensors, can be used with earlier exhausts fitted with 18mm sensor.
Includes the required O2 sensor extension cable for 10-16 Touring models.
Fits: > 10-16 Touring (with pre-2010 exhaust)
