Introducing our B58 M140i, M240i, M340i, M440i Carbon Intake System!

Components:

Prepreg Carbon Filter Housing and integrated MAF tube
Prepreg Carbon Scoop
Prepreg Carbon filter shroud
HIgh Flow Double Cone Urethane Filter
Double layer main heat shield
Double layer secondary shield
Laser Cut Mounting Brackets
CNC Machined MAF Boss
Aluminium Inlet Cowl

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 filter housing itself uses our patent pending "Venturi" design which allows for laminar flow from the filter to the outlet - by avoiding turbulence we reduce the drag on the turbo.

A lot of attention was placed on the heat shielding since the intake is located next to the exhaust manifold. For this we used a double layer main shield with a silver finish on the exhaust side and black on the intake side. The silver layer reflects radiant heat from the exhaust and the black layer absorbs and radiant heat on the inlet side. The air gap between the two layers acts as an insulator to stop the conductive heat spreading to the inner layer. Furthermore - the filter housing has a carbon shroud to block the convective heat coming from the exhaust. There is another smaller double layer shield which protects the inlet side from immediate heat soak.

Finally we have a carbon scoop which fits behind the grill. This directs ambient airflow straight into the OEM ducting which then directs it to the intake area. On the road - this ensures that the filter area - blocked from the engine by the heat shields is saturated with ambient air to keep the IAT's low.

All components combine to provide a more efficient airflow path whilst maintaining low inlet temperatures.
