 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 the OUTLAW HiFlow 425 Air Cleaner and most other aftermarket Stage 1 Air Cleaners*.  It can even be used with the stock air cleaner.

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 air!

E-Z Install

Fits Most Sportsters 1991 & Up (except XR1200)

Fits Big Twin Evo's

FITMENT:  

*If your air cleaner system will accept the Stock OEM breather bolts that have a 3/8" diameter nipple, then this breather kit will allow you to route the hot oily air to the supplied filter that you can place anywhere you like.  

 Filter may, or may not, have a small loop in it.  This does not affect the aesthetics or installation choices.

 

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.

(also used a Vented Chrome Catch-Can, which you can see HERE)

 

Hope this will help someone else with their installation.

 

The pictures are as follows:

 

 

#1 - K&N air filter with nylon plug in hole where stock hose was.

 

 

 

#2 -  Stock hoses connected to hoses in kit, and exiting bottom of air filter housing through hole I had to drill.

 

 

 

 

#3 - Hose running on top of cam cover. ( I put a piece of split nylon wire wrap over rubber hose to protect it from heat and rubbing )

 

 

 

#4 - Hose routed on left side of oil pressure switch.

 

 

 

 

#5 - Hose routed on left side of rear brake control cylinder.

 

 

 

#6 - Hose coming straight down and secured with wire tie. Catch can is very secure and easy to access.

 

 

 

 

#7 Air filter installed. There is plenty of room for it and the breather hoses. Works great, and I think it looks fairly good.
