Stage 3 Anodized Black Breather Bolts Harley-Davidson TWIN CAM

This pair of Outlaw Breather Bolts will really clean up your ride!  No more hoses or filter.  The filter is built into the bolt.

The EPA has required Harley to route dirty, oily crankcase air back into the air cleaner compromising the performance of your engine. This vents it without compromising the performance or longevity of your motor.

Caution:  Motorcycles modified with this DK Custom Products High-Performance part may not be legal for public highway use in some areas.  The user shall determine suitability of this product for his or her use.

With the Outlaw Racing Breather Bolts you will experience a slight performance increase.  This is because engines like Cold Dry air!

Also available in Brass & Polished Aluminum.  These are a must-have when doing your Stage 1 upgrade.

Customer Reviews

clean and effective Review by jim
I installed these on my 2019 Softail Slim. I prefer these to the hose and filter or catch can option as it looks much neater. If I were to have an oil blow by mess then I can always change to the hose and filter set up. So far not one drop from this motor. (Posted on 7/17/2019)
Sweet Review by dahomes
Easy to install and have not had any oil blow back. (Posted on 5/16/2019)
Cheap, and effective Review by Rob
Install is a breeze, and they look great!
Only downside for me is that some oil blows through the filter, and onto the intake manifold and battery cover on longer rides. (Posted on 10/26/2017)
