This is Not designed to fit the Ventilator covers that fit the tapered filter elements, like found on most M8's. (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.


E-Z Installation with Step-by-Step Instructions.

Genuine K&N Filter with Million Mile Warranty.

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

Fits Milwaukee-Eight Models.

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

Replace the Restrictive stock air cleaner on your M8 and wake it up!

The 6061 Billet Backplate was designed for maximum flow and minimum impact on rider leg clearancewith only 2.5" from Throttle Body 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.

Harley routes 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 with a Variety of Other Looks.
