Low and midrange Billet
Velocity Stacks Patented Quick change, high velocity design. Super seal design keeps all the pressurized air IN the airbox. Note from Marc: The "Midrange" Race stacks are my choice for any street and most track use. The additional 4-5 HP across the 7000 to 9000 rpm range augments the 2 True HP gain at 10,000 rpm. |
MIDRANGE Billet Stacks VEL-K96-2525 Extra strong Midrange and about 1-2 topend hp. |
