The high-flow Retro-Skinny Velocity Stack Air Cleaner with filter element by RXC Design is a styled up take on the classic velocity stack intake carefully designed and CNC milled out of one piece of billet aluminium. The intake gives an old school look while providing more performance. These ship with the included high-flow air filter element so you can bolt on and ride. Performance: Because of the conical geometry of the high-flow element together with the conically shaped intake, air enters at a higher speed and pressure into the motor. More air being delivered equals more power. The length and body shape also provide a more direct input which results in a more intense flow and less turbulent air. The intake is engineered so that cooler air, further away from the the motor (as opposed to the stock Harley intake), is sucked into the motor. Colder air is denser and also contributes to more oxygen available to burn. Using a stock Sportster 1200 as an example on the dyno: We see
