Eventuri’s approach to the transverse B48 is to treat the intake as one engineered system rather than a filter swap. In place of the factory airbox goes a patented carbon fibre Venturi housing with an integrated MAF tube, which does the real work: it shapes the air into a smooth, laminar path from filter to turbo inlet, behaving like a large velocity stack instead of a cone sitting in turbulent air. The payoff Eventuri measured is a 0.2-second improvement in the 60-130 mph run on an otherwise stock car.
Inside the housing sits a bespoke Generation 2 dry filter, and the housing seals against a carbon front duct that has been maximised in volume to take restriction out of the flow path. Because it is sealed, the duct only ever feeds the filter ambient air, so intake temperatures stay steady across most conditions and the turbo can run a lower waste-gate duty cycle. Aluminium inlet cowls and laser-cut stainless brackets tie the system into the engine bay precisely, all finished in Eventuri’s signature prepreg carbon.
