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

Part Number: 737123297153

The Bull Boost Performance 4" Red Billet Turbo Inlet Velocity Stack Adapter is designed to improve turbocharger airflow efficiency while adding a bold, performance-focused appearance to your engine bay. Precision-machined from high-grade billet aluminum and finished in a durable red anodized coating, this inlet guard is built for both style and function in high-performance setups.

The smooth bellmouth velocity stack design promotes efficient air entry into the turbo compressor housing by reducing turbulence and minimizing boundary layer separation at the inlet. This helps support more consistent airflow, improved spool characteristics, and enhanced overall induction efficiency in turbocharged applications.

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

Designed for 4" turbo inlet applications, this unit is compatible with GT3582 and similar turbochargers, as well as select naturally aspirated intake configurations requiring a 4" inlet.
