This is Not designed to fit the Ventilator covers that fit the tapered filter elements. (see photos)

You can run this 828 with a Ventilator Cover you already have, or you can order a Ventilator Cover from Harley directly, or from a HD Dealership...Just make sure it is a cover that is like those pictured in the photos here...NOT one made for the tapered filter element.

Filter is re-usable.  Simply wash, let dry, & apply oil.  See Filter Service Care Kit HERE.

Fits Carbureted & EFI Dyna, Softail, & Touring Twin Cam Models.

This is a must for at Stage 1- IV Upgrades.

 You can upgrade to the Outlaw HiFlow 828 Air Cleaner without doing any dyno work or adding tuners IF you leave the stock exhaust in place.

Replace the Restrictive stock air cleaner on your Twin Cam and wake it up!

The 6061 Billet Backplate was designed for maximum flow and minimum impact on rider leg clearance, with only 2" from Throttle Body/Carb to Outside Surface of Cover.

Included: Your Choice of Brass, Black or Polished Aluminum Breathers.  Or you can choose one of the Hose & Filter Breather Systems for venting- The Traditional or the Discrete.  To see full details on ALL these choices Click HERE.

When choosing between the 6 Breather systems, it is helpful to know-

1.  All three Breather Bolt function the same, it is just a matter of which color you prefer.

2.  All of the Hose and Filter or Catch-Can  Breathers function the same with the Outlaw Air Cleaners, it is a matter of which system you like the looks of the best.

The Transformer™ is the Ultimate External Breather System, that Doubles as a Support Bracket and can be Transformed into an EPA (Emissions) Compliant System. It fits all Outlaw Air Cleaners.

The EPA has required Harley to route dirty, oily crankcase air back into the air cleaner compromising the performance of your engine. The Outlaw Breathers vents it without compromising the performance or longevity of your motor.


This Performance Air Intake is CNC cut by DK Custom Products in the USA.  This particular Model is for use with a Straight Ventilator Cover.  See photos.

This is a Sleeper Mod.  Once Installed with a Ventilator Cover, You Cannot See a Visual Difference. 

EXCEPT, it is Lower Profile AND It Has Much Better Flow of ONLY CLEAN Air, so

There is A Very Nice Performance Improvement.

This HiFlow Performance 828 Intake System is also available in a Variety of other Looks.  Click HERE to See Them.

Great Product Review by ROVA
2015 Road Glide Ultra CVO
My bike has the Screamin' Eagle Street Performance High-Flow 58mm EFI Throttle Body. This product fit perfectly. (almost too perfect.). I was concerned that a spacer was needed so I called DK customer support. They confirmed that everything is good and provided pictures with my exact throttle body. I almost bought the cool looking see through, non K&N air cleaner from another company. I am very happy with my decision to go with DK customs line of air cleaners. Its an easy one stop, low cost complete solution to EBS.
