In the picture below you can see one of many different places you can affix the filter. Please look at the additional pictures at the bottom to see how discrete this external breather system is.
An external Breather Kit is preferred with any Air Cleaner System. This allows for only clean cool air to go into the air cleaner and engine, increasing performance and engine longevity. This kit will work with ALL OUTLAW HiFlow Air Cleaners and many other aftermarket Stage 1 Air Cleaners*.
The EPA has required Harley to route hot, dirty, oily crankcase air back into the air cleaner compromising the performance of your engine. This vents it without compromising the performance and 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 this breather system you will experience a slight performance increase. This is because engines like Cold Dry air!
You can also use a hose to route directly to the ground.
*Fits ALL Outlaw Air Cleaners. For aftermarket A/C's, If your air cleaner system utilizes a support bracket that is no thicker than 1/4", this will fit. If you A/C uses a backplate that bolts into the heads, this will not fit. You will need to use the Breather Bolts or standard Discrete System to allow you to route the hot oily air outside your combustion chambers.
Does not work with OEM, Screamin Eagle, most S&S, Arlen Ness, Roland Sands , etc... If you have questions about fitment, please email with a photo, link, or part number of the air cleaner on your bike.
