• Laminar Flow Technology - An internal velocity stack shaped structure serves to smooth and accelerate the air column. The result is an increase in flow and easier, more consistent jetting.
• A Unique K&N Filter - This filter, produced by K&N exclusively for Kuryakyn, is a round, slightly tapered air filter with the added benefit of filter material across the end of the filter. All other air cleaners block off the end of the filter so they are only able to breath through the sides. This design will drastically improve flow without the need to overwhelmingly increase size.
• Five Spoke Screw Pattern Styling - This is the first design in what promises to be an exciting series of air cleaners. The Hi Five cover is a five spoke, slotted design with both side and frontal openings to provide generous air-flow through the unique K&N filter.
• These kits come complete with everything you need for a sanitary installation, including the jets!

Take advantage of this spectacular illusion, it is definitely the first of its kind. Throw the switch and the cover is instantly transformed. The smooth, mirror finished outer panel becomes a vortex of lights. The Infinity Streamliner can be installed on any standard body Hypercharger air cleaner quickly and easily in under an hour.
Seven Color L.E.D. technology operates in three stunning modes:

• Single color steady illumination.
• Single color flashing illumination with rheostat adjusted variable rate.
• Paint Mode: All lights, in unison, continuously fading into and out of each of the seven colors (red, lime, ice blue, sky blue, dark blue, purple, green). The rheostat can be used to adjust how quickly the lights fade from one to the next.

L.E.D. technology means there is no need to worry about draining your bike's battery (provided the battery is in good condition and the lights are not left for more than a couple hours). Get out there, the crowds are waiting!

Note: This is not a complete air kit! Must be used with Kuryakyn standard body Hypercharger air cleaner only!

Note: Will fit Vulcan 805 Classic.
