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

Part Number: 720595369589

The Bull Boost Performance 4" Polished Billet Turbo Inlet Velocity Stack Adapter is engineered to maximize airflow efficiency while adding a clean, high-performance appearance to your turbo setup. Precision-machined from high-quality billet aluminum with a polished finish, this velocity stack is designed for improved induction performance and long-term durability in demanding applications.

Featuring a smooth bellmouth funnel design, this inlet adapter helps reduce airflow turbulence and minimize boundary layer separation as air enters the turbocharger compressor housing. The result is smoother airflow delivery, improved induction efficiency, and enhanced turbo spool response under acceleration.

The integrated hex-style inlet guard provides added protection by helping prevent larger debris from entering the turbo or intake system while maintaining strong airflow capability for high-performance use.

Designed for 4" turbo inlet applications, this velocity stack is an excellent fit for GT3582 turbochargers and other compatible turbo systems, while also working with select naturally aspirated intake setups requiring a 4" inlet opening.
