FEATURES & SPECS:

  • Fits almost All Air Cleaner Systems that use the stock breather bolts
  • Your Choice of Aluminum or Black Finish
  • Includes 6 feet of hose for maximum flexibility in Catch Can placement

  • Made in The USA!

 

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.

Breather releif Review by Dale
I did a lot of research before purchasing this system. It did take some thought about how I wanted it installed and how I would route the hoses. The Screaming Eagle backing plate would need to be drilled for the hoses but I had a different Stage 1 filter that did not require drilling. The burning smell of oil is finally gone.

DK Custom Products catch can. Review by Robert G
I ordered this catch can system for my 2009 HD Electra Glide after reading reviews online regarding the oil blowback and the moisture condensation that’s going into my engine. After careful consideration and evaluating all the products on the market, I found this one to be the best and I am very happy with this product! Easy installation, and very successful in catching oil coming out of the breather box plus moisture condensation.

Thanks for the great product!! (Posted on 3/9/2023)

Easy install Review by Tom
Purchased the kit for my 2022 Tri Glide, with only 2300 miles on it. I didn't like the idea of hot oily air being fed into the intake. the install was straightforward , and the included instructions were good. With no baseline temps, I won't be able to tell if there is a change. But, at least there won't be oily, hot air being sucked into the cylinders. (Posted on 2/17/2023)

Love it. Great Value. Good for the bike Review by Steve G
Just installed a catch can External Breather System on my new 2022 Heritage FLHCS. Only have about 400 miles on the bike, but I wanted to take advantage of the benefits of the EBS system (reduce carbon build up and put clean, cool air into intake). This is my second EBS install. Put one on my 2018 Heritage when the 2-year warranty expired in 2020. Didn't want to wait to get the benefits of the EBS on my new ride. THANKS DK Custom Products. (Posted on 11/30/2022)

I so happy knowing that all that crap isn’t being sucked back into my engine. I never realized how much blow by some of my engines had until I went stage one. Stage 2 even worse. Install was easy and the kit provided everything, no unnecessary trips to hardware stores or auto stores. Service and staff were excellent. U won’t even know I’ve installed one. Can’t c it, get creative and you’ll be all giddy every time u look at your work. Ride safe everyone..enjoy every second of each ride. (Posted on 3/8/2022)

Catch can system Review by Johnny
So glad I found this product! I installed the breather system with no problems on my 2020 SGS. Took it for about a 100 mile ride soon after. When returned home I checked the catch can being curious. The can contained about two tea spoons of an oily water substance. Also the bike felt much stronger and no oil under my breather ! If you are considering installing this product GO FOR IT !! Well worth the $ !! Wish I had done this sooner ! I have now ordered one for my dad's 2017 SGS as well !! I spent good money upgrading to a stage II and having dyno work done glad I'm not building carbon on the pistons and killing my tune !! Thanks DK Custom Products!!! (Posted on 2/24/2022)

Almost the perfect kit Review by DJMAD
A quality product at a fair price. Excellent communication from DK and super fast international delivery.
The kit is missing a couple of simple inclusions. I know where to mount the can is a very personal choice, but a 35 mm P clamp fits the can perfectly and should be included as part of the mounting hardware.
Also a simple grommet to plug the standard air cleaner hole left by removing the snot pipe would also be easy to include.
Overall a fantastic product. (Posted on 10/25/2021)

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)

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)
