Welcome to a new era in race manifold technology. Weiand has raised the bar on intake manifold design through the use of industry leading Computational Fluid Dynamics software. Technology this advanced has typically only been used in the aerospace industry for aircraft design. Weiand has taken this technology and designed a new line of Track Warrior manifolds perfect for aggressive street machines and Comp/Super class big block power plants. Computer engineered and dyno proven to produce more horsepower and torque as a result of superior cylinder to cylinder distribution gives this piece the edge over the competition and ensures safe, consistent air/fuel ratios for your engine.
