HurricaneFlow Air Cleaners for Sportsters and Buells

 

Big power requires big flow, and that's what the HurricaneFlow air cleaner is all about. From it's computer designed billet aluminum backplate to the extra large K&N element, this air cleaner is designed to PERFORM.

 

It's all about minimizing restriction and smoothing the air flow. The big K&N element  serves up filtration and diffusion in abundance, with LOTS of surface area to virtually eliminate restriction. The CNC-machined billet backplate recesses the element to smooth the transition as the air exits the media, and then takes the air around a specially designed huge radius ring to both boost velocity and eliminate turbulence. Even the size, shape, and locations of the stand-offs were chosen for their flow characteristics.

 

The result? Even on very mild motors, our dyno testing shows a significant improvement over the stock or SE offerings. With hotter motors, the difference gets even bigger!

Available for:

2004-up Sportsters (including fuel injected models)

1991-2003 Sportsters

1995-2002 Buells

 

S&S E and G carbs also available. Pricing is the same as our normal models.  Please call 303-702-1600 to order

 

Custom configurations available, please call. For example, we can have your air cleaner powder coated, or we can configure your forward offset air cleaner with an alternate sized element for even more knee clearance.

 

Note 1: to maximize power and reduce carbon build-up, HurricaneFlow air cleaners do not route the blow-by from the breathers into the intake tract the way the stock air cleaner does. We recommend routing the head breather outlets to a small filter (to absorb the moisture component), or to a catch can. See below for the accessories needed to do this.

 

Note 2: HurricaneFlow air cleaners are for off-highway, closed course competition use only and are not legal for sale or use on pollution controlled motor vehicles.

 

Note 3: HurricaneFlow air cleaners are designed to bolt up to the factory CV carburetor. The screw lengths are sized for maximum thread engagement and strength. When used with a Mikuni carburetor with a CV adapter ring, the supplied screws may be slightly too long and require shortening.

 

HurricaneFlow Air Cleaners For 2004-up Sportsters

 

For the 2004-up Sportsters, the HurricaneFlow is available with a 2" element in an on-center or forward offset design, or for the really big horsepower motors we offer it with a giant 3" element (available in the in a forward offset design only due to the knee clearance required). All versions use a billet front plate with a stepped perimeter to smooth the air flow as it passes through the media, and it also mounts your stock cover for that stealth look. These do work on 07 and up fuel injected Sportsters as well. You do not need a support bracket on fuel injected Sportsters but you do still need a breather kit.  You also will need an extra bolt that is available below.

The new NRHS billet round air cleaner is here!

 

 

 

 

 

You asked for it so here it is! The new NRHS Sportster billet round air cleaner is now available. CNC machined from solid billet aluminum and uses a genuine K&N filter. This filter flows as good as it looks

 

Just like our other filters it's all about minimizing restriction and smoothing the air flow. The big 2" K&N element  allows the air to flow through in abundance, with LOTS of surface area to virtually eliminate restriction.  This filter has been dyno proven to support engines making in excess of 90+ horsepower. And the CNC machined radius ring boosts both velocity and reduces turbulence.

 

And for that custom look we have many options available for the center section. Everything from showing off your NRHS 1250 power to custom lettering and numbers are available or flip it over for that stealth look!!

 

Prices start at $209.95 for a billet filter and center section as shown above. Custom covers like the black one shown above are available for a modest charge as is anodizing in almost any color imaginable.

 

 You also will need a breather kit and support bracket kit. 2007 and newer do not require a support bracket.

 

Fits all Sportsters equipped with a CV or Mikuni carb and also 2007 and up with fuel injection!
