O2 Sensor Bung Reducers 18mm To 12mm Pair

Namz started to produce our oxygen sensor extensions since many customers had asked how they could fit their custom exhaust system from their 2009 fl onto a new 2010 fl models.The kit also works perfectly for all 2012 fxst & dyna models allowing the use of older style pipes.The new sensors are also in a different location, much further back on the head pipe thus making the need for a longer harness.Our oxygen sensor extensions allows the use of a 2009 header to fit onto 2010-up models and includes 18mm to 12mm bung adapters & a front plug-n-play harness extension to allow for easy installation.Our front o2 extension harness kits have been tested and designed by our engineers to work & fit perfectly.Simple installation and are intended to be installed with 2009 headers/exhaust systems & all 2012 fxst & dyna models.
