548247 O2 sensor inline enrichment device

This Namz O2 sensor inline enrichment device is a simple and effective way to tune the fuel mixture on your 2006 Dyna. It works by adjusting the air-fuel ratio within a range of 14.6:1 to 14.2:1, helping to cool down the engine and improve throttle response by richening up the lean factory settings. It is a great choice for riders who have added an exhaust or air cleaner and want a bit more fuel without jumping into a full-blown aftermarket tuner. This device is sold individually and installs directly in line with your stock O2 sensor. It is a straightforward, plug-and-play solution for improving the rideability and longevity of your early EFI Dyna.
