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

Part Number: 737123297160

The Bull Boost Performance 4" Black Billet Turbo Inlet Velocity Stack Adapter is designed to improve airflow efficiency while providing added protection for your turbocharger inlet. Precision-machined from high-grade billet aluminum with a durable black finish, this adapter combines performance-focused design with a clean, aggressive engine bay appearance.

The smooth bellmouth funnel design helps reduce inlet turbulence and promotes more stable, high-volume airflow into the turbo compressor housing. By minimizing boundary layer separation at the inlet, this velocity stack supports improved induction efficiency, better spool characteristics, and more consistent boost response in performance applications.

The integrated hex-style guard helps reduce the risk of larger debris entering the intake system, adding an extra layer of protection for both turbo and engine components without significantly restricting airflow.

This unit is designed for 4" turbo inlet applications, including GT3582 and similar turbocharger setups, and can also be used in compatible naturally aspirated intake configurations.
