Looking to eliminate one of the biggest airflow restrictions before your turbos?

The factory turbo inlets are designed around packaging and manufacturing constraints, creating unnecessary restrictions as air enters the turbochargers. Whether you're running stock turbos or pushing a high-horsepower build, improving airflow before the compressor can make a noticeable difference in turbo efficiency and responsiveness.

The Ultra Flow Billet CNC Turbo Inlets replace the restrictive factory inlets with precision CNC-machined billet aluminum components featuring significantly larger internal diameters and an optimized flow path. The result is smoother airflow, reduced turbulence, faster turbo spool, and increased airflow capacity to support everything from daily-driven cars to high-boost performance builds.

Higher Flow.
Faster Spool.
Engineered to Perform.

Why these Billet CNC Turbo Inlets

Airflow is everything when it comes to turbocharged performance.

Precision-machined from aircraft-grade 6061 billet aluminum, these turbo inlets feature an enlarged, high-flow internal design that reduces restriction before the turbocharger. By allowing the turbos to breathe more efficiently, they improve throttle response, increase turbo efficiency, and help support additional horsepower and torque.

Unlike factory plastic components, billet aluminum provides exceptional strength, excellent heat resistance, and long-term durability while giving your engine bay a premium motorsport-inspired appearance.

Designed specifically for the BMW S58 platform, these turbo inlets are compatible with both factory-location turbochargers and most upgraded hybrid turbo systems, making them an excellent upgrade whether you're just beginning your build or chasing maximum power.

Less restriction.
More airflow.
Built for every stage of your S58 build.
