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 U.S.A.

Fitment Notes
