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.

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

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

 2.  All  the Hose and Filter - Catch-Can EB Systems 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.

This System comes with a Billet Aluminum Black Finned Cover. 

These are also available with a Polished Finned Cover, which you can see HERE,  Contrast Finned, which you can see HERE, and No Cover, so you can use your factory Ham-Can Cover (or no cover at all, or a cover you design).  See the No Cover 828 HERE.

See the full spec's on the K&N Filter Element HERE.

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

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

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.
