Eventuri Carbon Fibre Intake BMW B58 M140i/M240i/M340i

  

Eventuri intake for BMW B58 M140I M240i and M340i. The B58 Eventuri intake system is another example of our "Complete System" principal.

It demonstrates the perfect balance between allowing for unrestricted airflow with our open filter housing whilst maintaining low IAT by cold air saturation with our scoop and shield combination. Every detail has been meticulously developed from the prepreg carbon pieces to the double layer heat shields. This intake sets a new benchmark in design and craftsmanship for the B58 platform.

The B58 Eventuri system uses our Patented Carbon fibre Housing which provides an aerodynamically efficient airflow path from the filter to the turbo. Not just another cone filter with a heat shield but a unique design which invokes the Venturi affect and maintains laminar flow conditions to reduce the drag on the turbo.

The filter housing comprises of a high flow filter, aluminium cowl, laser cut bracket, carbon heat shroud and the carbon pod itself, which extends to incorporate the MAF sensor and turbo tube. The carbon pod shrouds the reverse mounted filter and smoothly shapes the airflow down to the integrated MAF 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 - below is a diagram to show the comparison between our patent pending design and a regular intake system. The carbon filter housing and the inlet tube have been integrated to be 1 continuous piece. This reduces the number of internal interfaces and allows for smoother airflow to the turbo. The diameter of the tube smoothly transitions from the required diameter at the MAF sensor end to the larger diameter of the turbo inlet.

The Carbon filter housing is mated to a carbon heat shroud and an additional aluminium shield which stop the convective heat from the exhaust manifold saturating the filter. This coupled with our comprehensive double layered heat shields combine to provide a very effective cold area around the filter opening.

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. The following video explains the design features behind our M2 scoop which directly apply to the B58 scoop.

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.
