Air Intake - Filters and Air Horns

Air Horns

Our Air Horns are made to be flexible, just like our ITBs.  They are CNC machined to the highest tolerances and red anodized for looks and durability.  Our filters are custom made for Extrudabody by UNI Filter®.  Find out why foam filters make hp here.

For most customers, the 3" diameter Air Filters simply clamp right onto the Air Horns for an easy fit and high flow. 

Others might put our Horns inside a custom intake plenum, utilizing the horns smooth air into the ITBs. 

Or, some might put our Horns on top of our Extensions and make a longer Air Horn in the process. 

If you want to get every last pony from your engine, buy Air Horns one size up from your ITBs (e.g., 50mm Horns for 45mm ITB) and some Extensions the same size as your ITB.  Then, port or angle bore the Extensions to create a tapered Air Horn.  You can also do a tapered reduction where 45mm ITBs can be tapered to match a 40mm manifold.  For more information on how to build tapered velocity stack systems, click here.                  

Extensions paired with Air Horns essentially create a longer air horn. 
Chose 25mm, 50mm, or combine a couple to tune your intake just how you need.
