Frequently Asked Questions

Why do I need an O2 sensor extension?

Modern Harley head pipes locate oxygen sensors further back than older pipes. Extensions let you run vintage headers on newer bikes without relocating the sensor.

Will this fit my 2010 Touring if I install 2009 pipes?

Yes — this extension kit is designed specifically to adapt 2009 headers to 2010-up Touring models.

Does this work on 2012 Dyna and FXST models?

Yes — all 2012 FXST and Dyna models can use older-style pipes with this extension kit.

Are connectors included?

The harness has pre-installed terminals but no connectors — you will need to match them to your factory connector or splice into your existing harness.
