Feed both S58 turbos through one massive 6-inch filter with the RVNG MonoFlow carbon fiber intake. Instead of running a separate filter and pipe to each turbo, the MonoFlow brings both sides together into one large carbon fiber intake pipe for more airflow, more turbo sound and a much cleaner engine bay.
This is more than a pair of filters and intake pipes. The complete system includes larger 87mm and 83mm aluminum turbo inlets along with a carbon fiber air funnel that directs outside air from the front grille toward the filter.

Single-Filter MonoFlow Design
The S58 normally uses two separate intake paths. RVNG takes a different approach by using one 6-inch high-flow filter and a single carbon fiber pipe to supply both turbochargers. This gives the engine a larger shared source of incoming air while opening up the intake and turbo sound.
The system is available with matte or gloss carbon fiber, along with a red or black filter.
Larger Turbo Inlets
The included 87mm and 83mm turbo inlets replace the smaller factory inlet sections. They are made from lightweight 3D-printed aluminum and use a dimpled inner surface designed to help manage airflow into the turbochargers.
Dyno Results
- RVNG MonoFlow Intake: 527.3 hp and 504.9 lb-ft of torque
- Stock Intake: 503 hp and 479 lb-ft of torque
- Measured Difference: 24.3 hp and 25.9 lb-ft of torque
These are RVNG's measured results. Actual gains will vary based on the vehicle, tune, fuel, turbo setup and testing conditions.
Turbo Compatibility
- Compatible with factory S58 turbochargers
- Compatible with select hybrid turbos from Pure and LM
- Not compatible with Spool turbochargers
If your car has upgraded turbos, include the turbo brand with your order so compatibility can be checked.
