4" Single Turbo Velocity Stack with 1/8" NPT and 12AN Intake Port

ITS HERE! our very own single piece billet aluminum 4" velocity stack with 1/8" NPT port and 12AN intake port!  This velocity stack offers more than any other velocity stack on the market.  Milled from a single piece of 6061 T6 aluminum our 4" velocity stack adds performance, style, as well as solving many issues associated with vent to atmosphere catch can systems.   Performance is gained by smoothing out the air and accelerating the charge air as it enters the turbo.  A major benefit over a simple screen type that covers your turbo.  We have incorporated a 1/8NPT port at the top of the velocity stack to allow for either a nitrous nozzle or methanol nozzle for added horse power and torque.   Style, our velocity stack is milled from a single block of 6061 aluminum that offers amazing style and a screen that is milled directly into the velocity stack.  This will help from larger objects from entering the turbo intake with out breaking of degrading like the simple band screens offered on
