***Due to current market conditions and a large discrepancy in raw materials for finished components, we can not guarantee your product may not be out of stock. Although we try to stock many items in our multiple warehouse and use multiple distribution channels, this is sometimes unavoidable. If you are in a rush for a product, we suggest you text, email, message, or call us for availability. We will provide an ETA (based on vendor provided info) if an item is not currently available.


Typical air filtration devices create unfavorable geometry that introduces turbulent vorticles and causes a choking point at the inlet entrance. Velocity stacks utilize smooth-radius, larger flange diameter filters to create a geometry that eliminates this choke point, thus vastly increasing volumetric air flow.  Each velocity stack is designed to allow optimal efficiency using computational fluid dynamics (CFD) software and is manufactured from PA66 glass-filled Nylon to reduce heat soak but also retain rigidity in a lightweight form.
This velocity stack is intended for use with 3.5" (89mm) OD tubing and a 6" (152mm) ID filter. We use this piece in our 2006 - 2015 Civic intake systems.
