NAMZ Custom Cycle O2 Sensor Extension & Bung Reducer Kit 12" - Harley Touring, Softail & Dyna
About NAMZ Custom Cycle
NAMZ Custom Cycle builds plug-and-play wiring harnesses, extension kits and electrical components for Harley-Davidson. Its handlebar extension and connector kits are what make an ape hanger or bagger bar swap a bolt-in job instead of a splicing project.
This NAMZ Custom Cycle O2 sensor extension kit is designed to allow the use of older-style exhaust headers on newer Harley-Davidson models. It addresses the issue of relocated O2 sensor positions on 2010-up head pipes by providing a 12-inch extension harness. The kit also includes bung reducers and pre-installed terminals, making it ideal for custom exhaust fabrication and seamless integration.

When you're upgrading your Harley Touring, Softail, or Dyna with a custom exhaust, you might find that the O2 sensor bungs on older headers don't align with the sensor locations on newer motorcycles. This NAMZ Custom Cycle kit provides a comprehensive solution, extending your O2 sensor harness by 12 inches and including bung reducers to ensure a perfect fit. This means you can achieve your desired exhaust look and performance without compromising your bike's crucial engine management system.

Streamlined Installation for Custom Exhausts
This kit is a must-have for riders looking to achieve a specific exhaust setup that might not be a direct bolt-on due to O2 sensor placement or size differences.

Common questions
Why would I need an O2 sensor extension kit?
Newer Harley-Davidson models relocated the O2 sensor position further back on the head pipe. Extensions let you keep older headers while reaching the new sensor location, ensuring proper engine function.
Can I use 2009 headers on my 2010 or newer Touring model with this kit?
Yes, this kit includes the 12-inch extension harness and bung reducers needed to adapt 2009 FL headers to fit 2010-up FL models where the sensor location has shifted.
Are electrical connectors included with this kit?
This kit includes pre-installed terminals, but the final connectors are not included. This allows for custom splicing into your bike's existing wiring harness.
