An External Breather System (EBS) 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.

With this breather system you will experience a slight performance increase.  This is because engines like Cold, Dry, Oxygen Rich air!


The top of the Catch Can is attached to the hose by a zip tie or hose clamp (both supplied w/ the kit).  The bottom of the Catch Can threads to the top. 

Anytime you want, you can un-screw the can portion, squeeze any oil/gunk out of the foam filter and then thread it back together.

The top of the Catch Can is vented, letting the air escape, while the foam filter catches and holds the oil.

The Catch Can is 1 3/8" in diameter and 2 1/4" tall.


E-Z Install

Fits Most Sportsters 1991 & Up (except XR1200)

*Fits ALL Outlaw Air Cleaners.  For aftermarket A/C's, If your air cleaner system utilzes a support bracket that is no thicker than 1/4", this will fit.  

There are Optional Black Fiber & Stainless Steel Braided Hose  & Black or Chrome Hose Clamp Covers, and blacked-out hose clamps if you prefer that look to the Black Hose and plain hose clamps or zip ties.

Customer Reviews

She's a Spitter Review by Chops
Originally went with breather bolts but quickly found out my bike (some are worse than others) is a spitter, the breather bolts had to go. The black catch can and hardware provide a clean look, wish the banjo bolts and fittings were black (Guy's?) but the chrome goes well with my chrome air cleaner cover. Good price and quick delivery, happy customer!
Thanks Dev and Kev. (Posted on 8/26/2017)
