Pair of Velocity Stacks for 40 mm Dual Body Carburetor

Direct airflow: the dual body carburetor velocity stacks without mesh

Increase the efficiency of your intake system with this pair of intake horns specific for 40 mm dual-body carburetors. These dual body carburetor velocity stacks are designed for Alfa Romeo-derived engines equipped with Weber, Dell'Orto, or Solex systems. Unlike shielded models, this mesh-free version allows for totally free air intake, minimizing any restriction and promoting a faster, more uniform air column toward the fuel ducts.

Functional satin aluminum design

These dual body carburetor velocity stacks are made of aluminum with a satin finish, providing a lightweight and technically reliable component. The characteristic funnel-shaped mouth is designed to channel the maximum possible air volume, stabilizing the flow before it enters the throttle body. Thanks to the flat, pre-drilled base flange, mounting on 40 mm carburetors is precise, ensuring a perfect mechanical seal without duct interference.

Product technical specifications:

• Compatibility: Ø 40 mm dual body carburetors (Weber, Dell'Orto, Solex).

• Material: Satin aluminum.

• Configuration: Open model without protective mesh.

• Application: Alfa Romeo engines and street or track sports tuning.

• Package contents: Pair of velocity stacks (2 pieces).

Maximum performance for sports intake

Installing dual body carburetor velocity stacks without mesh is the preferred choice for those seeking maximum fluid dynamic yield. The geometric shape is specifically designed to eliminate turbulence that usually occurs at the intake edges, significantly improving throttle response at higher RPMs. Since the satin aluminum ensures good structural management, this set integrates perfectly into the engine bay of tuned historic cars, offering a racing look and direct mechanical functionality.
