An external Breather System (EBS) is preferred with any Air Cleaner System.  This allows for only clean cool, oxygen rich air to go into the air cleaner and engine, increasing performance and engine longevity. 

This kit will work with the All the OUTLAW HiFlow Air Cleaners, and most other aftermarket Stage 1 Air Cleaners*.  It can even be used with the stock air cleaner if it uses the OEM breather bolts with nipples.

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!

 

 

 When ordering, Choose a Machine Cut Aluminum Finish or a Black Powder Coat Finish.

The Machine Cut Billet Aluminum Finish that can be polished to a Mirror Finish.

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, empty out all the gunk, and then thread it back together.

 The top of the Catch Can is vented, letting the air escape, while the 4 Stage Filtration catches and holds the oil.

 The Catch Can is 1 1/2" in diameter and 2 5/8" tall.  For more details on the 4 Stage Catch Cans, Click HERE.

 

E-Z Install

Fits All Twin Cam & Milwaukee-Eight Models - 2000-Up Touring & Softail, 1999-Up Dyna 

*If your air cleaner system will accept the Stock OEM breather bolts with nipples, then this breather kit will allow you to route the hot oily air to the supplied Catch Can that you can place anywhere you like. 

 

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.

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.

I'm a Viet Nam Vet; I work as a Program Manager for MHEP and VP of Latin American Rider's Association Review by DREAD
This kit does exactly what it is advertised to do; excellent quality and craftsmanship. Outstanding follow-up and communication from DK in responding to any questions. I have a Screaming Eagle Air Cleaner and the modification was easy to figure out where I wanted to place my catch cam and route the hose. DK makes it simple to adjust whatever you ride to create a perfect fit. AND IT WORKS! (Posted on 9/17/2021)

One little change Review by Ed
I bought the M8 black catch can kit. The can itself is great, but I also went online after receiving the kit to search out a tee that was 1/4 - 1/4 - 3/8 to eliminate the need for the reducer going into the can. Everyone likes a clean look to the mods on their bikes and I think it would be a great upgrade to your kits in the future. No disrespect, just my opinion. I found the tee online in black plastic and stainless steel through soda companies as odd as that is. (Posted on 7/30/2021)

high quality catch can. Super easy install. Review by Sarge
I ordered the wrong can on line. The next day I called and a very pleasant lady took care of me and stopped the shipment and changed the can for me, saving me the hassle of a return. The catch can is of high quality and the install was super easy. I spent an enjoyable afternoon working on my Road King. highly recommended. (Posted on 7/22/2021)

No need to fumble around the hardware store looking for parts and hoses. This kit is complete! If you can drill a hole through sheet metal, you qualify:-). Save your M8 from oil vapor sludge. Get this kit. The catch can is great quality, too!! (Posted on 6/22/2021)

Does what it’s supposed to - keeps the hot oil mist from coating the intake. My bikes now seems to idle much better & runs well. I’d definitely recommend it. (Posted on 6/19/2021)

Recently Installed Review by Jakal
Received my kit today and installed it. Up to this point I really thought my decel popping was due to an overly rich mixture. As soon as I installed the can, poof all my poping was gone my idle sounds more stable and overall it just seems like the breathing was just instantly better. Great product easy install, exactly what I was looking for. (Posted on 6/15/2021)

Excellent product Review by David
Easy to install and quality built. Only issue is the reducer could be a right angle, especially for the M*, so that the catch can can be placed right below the air cleaner. (Posted on 1/28/2021)

EBS w/black powder coated catch can Review by PeaceMaker
Installed on my ‘17 SGS, utilizing stock air box with K&N filter since I rather like the look of stock. Got tired of oil fouling air filter & seeping out of casing, no matter where I had adjusted the oil levels. Now, no more oil bypass into intake; just fresh/clean air. I’m mechanically incline & always taken longer than recommended when doin’ maintenance since I’m particular & think of other ways than standard instructions. I opted to install a grommet in stock air box for the exit hose to pass through & route down just behind rear brake reservoir underneath foot pad & ziptied to aft mounting bracket of reservoir. Also have DK’s Thunder Torque Inserts within my gutted megaphone slip-ons. Combined with my crankcase vented dip-stick. All n’ all, excellent product & customer service. (Posted on 1/25/2021)

Excellent Mod! Review by Rico
Installed with my OEM set-up. 30 minute super easy install. Looks good and functions as stated. I replaced the supplied plastic fittings with brass, but overall I would recommend for anyone who doesn't want hot oil fed back into their intake.
