Velocity Stacks

Improve airflow and throttle response with high-performance velocity stacks, also known as air horns. These precision-designed intake components smooth and accelerate airflow into your throttle body or carburetor, helping to increase horsepower and improve engine response across the rev range.

Available in a variety of lengths and diameters, velocity stacks let you fine-tune your powerband — shorter stacks favoring top-end power and longer stacks enhancing mid-range torque. Built from aluminum, carbon fiber, or composite materials, they also add a clean, race-inspired look to your engine bay.

Whether for street or track, velocity stacks are a proven way to enhance both performance and style in your intake setup.
