Eventuri BMW N20 Carbon Intake (125I, 220I, 320I & 328I) – EVE-N20-CF-INT
The Eventuri BMW N20 intake system consists of a number of components engineered to perform a specific purpose and fabricated to the highest of standards. Here are the details for each component and the design ethos behind them:
Each intake system consists of:
- Carbon Fibre Venturi Filter Housing
- Bespoke High Flow Non-Woven Mesh Dry Cone Filter
- Carbon Fibre inlet Duct
- Carbon Fibre Inlet Tube
- Carbon Fibre Front Scoop
- Laser Cut Stainless Steel Brackets
- High Quality Silicon Coupler
The Eventuri BMW N20 Carbo filter housing comprises of a high flow filter, aluminium cowl, laser cut brackets and the carbon pod itself. The carbon pod shrouds the reverse mounted filter and smoothly shapes the airflow down to the intake tube. This smooth reduction in cross sectional area invokes the Venturi effect where the airflow accelerates whilst maintaining laminar conditions. It can be thought of as a large velocity stack.
Our intake tube is crafted from 100% prepreg carbon fibre. The tubes smoothly carry the airflow to the turbo by ensuring there are no sharp or sudden bends. The smooth bend geometry ensures laminar flow is maintained from the filter to the exit. We have also incorporated the MAF sensor mount to the tube with a CNC machined MAF boss. By keeping the diameter the same as the stock MAF tube, the engine runs without any MAF related error lights.
The duct channels ambient air from the OEM air duct to the filter. It fits inside the OEM ducting system and smoothly transitions to the circular filter housing shape. In order to ensure a good seal against engine bay heat – it also has a flexible rubber edging around the opening which presses against the OEM ducting to create the desired seal. The duct was designed to have the maximum internal volume possible within the given geometry of the engine bay. This ensures that the filter housing is able to draw with minimum restriction.
The scoop was designed for maximum efficiency in directing the incoming air to the stock duct openings. Many aftermarket scoops have a large flat area almost perpendicular to the oncoming air – not great for channeling it into the ducts as the airflow just “hits” this flat portion and creates turbulence.
The Eventuri Scoops have been designed to sit directly behind the front grills to capture as much air as possible and with a continuous curve to the duct opening to ensure this airflow is efficiently channeled. Having an effective cold air feed to the filter is an essential part of our design. Simply having some heat shields alone would result in elevated inlet air temperatures as the engine bay soaks with heat – especially on this engine since the manifold is directly next to the intake.
