In 2005/2006 Rosson Racing and Rick Hench were the first to Design and Develop the Velocity Stack with a Filter Assembly. This is when the Rosson Racing Velocity Stack / Filter Assembly was introduced to the Retail Market for Sale. This product was not copied from someone else it was designed and perfected by Rosson Racing / Shane Rosson. My Efforts and numerous hours designing this product to bring it to the market can be seen in my Winner's Circle at and Drivers all over the World are running the "Rosson Racing Velocity Stack / Filter Assembly".
