Aluminum Bellmouth Velocity Stacks

A bellmouth velocity stack smooths air as it enters an intake, turbo inlet or throttle body, reducing turbulence at the opening. This collection covers the Vibrant Performance aluminum bellmouth velocity stacks in sizes such as 4 inch.

Tip

Weld or couple the stack to the inlet and add a filter or screen to keep debris out.

Why a bellmouth? A rounded entry flows noticeably better than a cut tube.
