NAMZ O2 Sensor Extension Harness Kit for 2010-2017 Harley-Davidson FL Touring Softail Dyna

NAMZ O2 Sensor Extension Harness Kit for 2010-2017 Harley-Davidson FL Touring Softail Dyna

Found the perfect aftermarket exhaust for a 2010-and-later Touring bike, only to discover it was designed for a 2009 model? This kit bridges that gap completely, letting riders run the pipes they want without rewiring anything or sourcing incompatible hardware.

Key Features

• Allows 2009-style exhaust systems with 18mm O2 sensor bungs to fit 2010-2017 FL Touring, 2012-2017 Softail, and 2012-2017 Dyna models that use 12mm bungs
• True plug-and-play design, plugs in between the front O2 sensors and the OEM wiring harness with no cutting or splicing required
• Includes a 24-inch front O2 wire extension with pre-installed mating connectors for direct plug-in installation
• Includes a pair of 18mm to 12mm O2 bung adapter reducers, all hardware needed in one kit
• Engineered to maintain proper O2 sensor signal to the ECM, no harm or interference to the motorcycle’s computer
• Made in the USA

Fitment Notes

• Installs on 2010-2017 FL Touring (Dresser), 2012-2017 Softail, and 2012-2017 Dyna models when fitting exhaust pipes designed for 2009 Harley-Davidson models
• Required because 2009 FL Touring exhaust systems use 18mm O2 sensor bungs while 2010 and later models use 12mm bungs, this kit handles the electrical extension and bung size reduction in one solution
• Covers front O2 sensor extension only, rear O2 sensor extension is not included
• Not required when fitting exhaust systems designed specifically for 2010-and-later models
