Frequently Asked Questions

Why do I need an O2 sensor extension?

Newer Harley models relocated the O2 sensor position further back on the head pipe. Extensions let you keep older headers while reaching the new sensor location.

Can I use 2009 headers on my 2010+ Touring?

Yes — this kit includes the extension harness and bung reducers needed to adapt 2009 FL headers to 2010-up FL models.

What's included in the kit?

12-inch extension harness with pre-installed terminals, bung reducers, and hardware needed for installation.

Do I need to solder or crimp anything?

The terminals are pre-installed. You'll need to connect them to your bike's O2 sensor harness based on your custom setup.
