Product details
OVERVIEW
The Eventuri F4X B48 intake system was developed through extensive real world testing and airflow simulation analysis. It uses Eventuri's patented Venturi housing with an integrated Mass Air Flow sensor section, giving the smoothest possible airflow path to the turbo inlet tube. The housing encases a bespoke Generation 2 dry filter that helps shape the airflow and maintain laminar conditions.
The housing seals to a front carbon duct that has been maximized in volume to reduce any potential flow restriction. Because the duct feeds only ambient air to the filter, intake air temperatures stay steady across most driving conditions. The result is better throttle response and a turbo that can work with a lower wastegate duty cycle.
SPECS
- Patented Venturi-profile carbon fiber housing with integrated MAF tube
- Prepreg carbon fiber construction
- Gloss black carbon finish
- Bespoke High Flow Generation 2 dry filter, housed inside the Venturi housing to shape airflow
- Retains the factory MAF sensor via the housing's integrated MAF section
- Sealed carbon fiber front duct, maximized in volume, feeds the filter ambient air only
- Allows the turbo to run a lower wastegate duty cycle for a given boost target
PARTS INCLUDED
