Eventuri BMW B58 Carbon Performance Intake (M140I, M240I, 340I & 440I) – EVE-B58-CF-INT
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. The secondary shield can also be seen in the above photo behind the turbo inlet pipe. During testing we found a temperature drop of over 90 degrees C across the shield which can be clearly seen in the thermal imaging video below. The effectiveness of the shield results in low inlet air temperatures whilst on the move.

The Eventuri BMW B58 Carbon 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 Eventuri B58 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:
- Prepreg Carbon Filter Housing and integrated MAF tube
- High Flow Double Cone Air Filter
- Aluminium Cowl for smooth airflow entry
- Prepreg Carbon Scoop
- Prepreg Carbon filter shroud
- CNC Machined MAF Boss
- Double layer main heat shield
- Double layer secondary shield
- Laser Cut Mounting Brackets
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.
