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

Part Number: 737123297177

The Bull Boost Performance 4" Silver Billet Turbo Inlet Velocity Stack Adapter is designed to maximize airflow efficiency while adding a clean, high-performance appearance to your turbo setup. Precision-machined from premium billet aluminum, this inlet adapter features a smooth bellmouth design engineered to improve airflow into the turbocharger while helping protect the compressor inlet from larger debris.

The funnel-shaped velocity stack promotes smoother air entry into the turbo by reducing turbulence and minimizing boundary layer separation at the compressor inlet. This allows for more efficient airflow delivery, improved turbo response, and enhanced overall induction performance under boost.

The integrated hex-style guard design helps prevent larger particles and debris from entering the intake system while maintaining strong airflow capability for high-performance applications.

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