BULL BOOST PERFORMANCE Gold Billet 4" Turbo Inlet Guard Velocity Stack Adapter Bellmouth Intake Hex

BULL BOOST PERFORMANCE Gold Billet 4" Turbo Inlet Guard Velocity Stack Adapter Bellmouth Intake Hex
Part Number: 737123297146

The Bull Boost Performance 4" Billet Turbo Inlet Velocity Stack Adapter is engineered to improve airflow efficiency and protect your turbocharger inlet with a precision-machined bellmouth design. Built from high-grade billet aluminum, this intake adapter is designed to reduce turbulence and promote smoother, more consistent airflow into the compressor housing—helping support better spool response and overall induction efficiency.

The smooth funnel-style bellmouth shape minimizes boundary layer separation at the inlet, allowing air to enter the turbo more evenly and efficiently. The integrated hex-style guard design also helps reduce the risk of larger debris entering the intake tract, adding an extra layer of protection for both turbo and engine components.

Specifically designed for 4" turbo inlet applications, including GT3582 turbochargers and similar setups, this unit is ideal for performance builds requiring high-flow intake solutions. It can also be used in naturally aspirated (N/A) intake inlet configurations where a 4" opening is present.
