The F97/F98X3M/X4M intake setup from BMW although awkward at first sight, is a very well designed system in the given space available. The flow path from the filters to the turbo inlets is very direct and does not change direction as abruptly as the usual OEM airbox designs. So instead of a complete redesign we focused on improving the OEM airbox with less restrictive flow and improved temperature efficiency. We have developed replacement drop in filters made from non-woven mesh which have a much higher flow rate as compared to the stock paper filters. To help reduce inlet air temperatures and force air into the airbox we designed large front scoops which sit behind the grills. The carbon scoops channel air into the ducts and effectively effectively de-restrict the inlet side of the airbox. The final piece is the carbon airbox lid which although doesn’t add to the performance, it does allow for a more audible induction sound and gives the engine bay a much needed aesthetic improvement.
The Eventuri Difference The M2 Eventuri system uses our Patented Housing which provides an aerodynamically efficient airflow path from the filter to the MAF tube. Not just another cone filter with a heat shield but a unique design which invokes the Venturi effect.
The Eventuri F87 M2 intake system consists of a number of components engineered to perform a specific purpose and fabricated to the highest of standards.
Intake Components
Prepreg Carbon Fiber Venturi Housing
High Flow Generation 2 Bespoke Cone Filter
Prepreg Carbon Sealing Duct
Prepreg Carbon Fiber Intake Tube with integrated MAF Sensor Mount
Prepeg carbon Fiber Air Scoop
Laser Cut Intake heat Shield
Laser Cut Stainless Steel Brackets
High quality Silicon couplers with BMW specification hose clamps
Carbon Intake Housing Assembly The filter housing comprises of a high flow filter, aluminum cowl, laser cut bracket 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 - below is a diagram to show the comparison between our patent pending design and a regular intake system. Further details can be read in the Technology page.
Carbon Intake Duct With Shield The filter housing is positioned with its opening sealed against this new carbon duct. This carbon duct has been designed to fit over the stock cold air duct and direct ambient air from the scoop into the filter. It seals against the engine bay heat whilst still allowing some air entry from the cold side of the engine bay where the hood meets the wing. In addition, there is a heat shield attached to the side which blocks the hot air from the radiator and the alternator from directly impacting onto the carbon housing. This shield reduces direct heat soak onto the carbon housing and therefore contributes in keeping IAT down.
Carbon Fiber Intake Tube Our intake tube is crafted from 100% prepreg carbon fiber. Each tube has an integrated MAF sensor mount and breather adapter which are CNC machined from aluminum. The inlet tube has been designed to provide a smooth path for the airflow to negotiate from the filter to the stock turbo tube. In order to clear the fan shroud we smoothly transitioned the cross section from a circle to an oval and maintained constant area. This ensures the airflow remains laminar and allows the turbo to function with minimal drag.
Carbon Fiber Intake Scoop 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 filters is an essential part of our design. Simply having some heat shields in place is not an effective means of avoiding heated air from entering the filters unless the shields create an air tight envelope around the filters. The scoops and ducts in our system combine to provide the filter openings with ambient air and maintain low intake air temperature.
