Eventuri Carbon Fibre Intake System for BMW M140i, M240i, 340i - B58
Unlock real performance from your BMW B58 with the Eventuri Carbon Fibre Intake System. Independent testing and customer feedback show proven gains of 12 to 15 hp and 14 to 18 ft lb, with dramatically improved airflow and consistently low intake air temperatures. This is the go to BMW M140i intake, BMW M240i intake and BMW 340i intake for drivers who want genuine power, premium materials and exceptional fit and finish.
Why choose the Eventuri B58 intake
- Open carbon fibre filter housing for maximum flow combined with targeted cold air feed to keep IAT low.
- Patent pending Venturi housing creates a smooth, laminar airflow path that reduces drag on the turbo.
- Double layer heat shielding and carbon shroud to combat radiant and conductive heat from the exhaust manifold.
- Carbon fibre front scoop loads the OEM ducting with ambient air for consistent performance on the road.
- Meticulous design and craftsmanship throughout. This is the benchmark carbon fibre cold air intake for the B58 platform.
Performance benefits you can feel
- Stronger mid range and top end thanks to reduced restriction and efficient flow to the turbo inlet.
- Smoother throttle response due to the integrated carbon housing and MAF tube that minimise internal interfaces.
- Reliable power delivery from sustained cold air saturation and class leading heat management.
How the Eventuri system works
The carbon filter housing and inlet tube are moulded as one continuous prepreg carbon piece. Diameter transitions are carefully profiled from the MAF sensor to the turbo inlet to maintain velocity without turbulence. The Venturi effect within the housing promotes laminar flow from filter to outlet which reduces the work the turbo has to do.
Comprehensive heat control is built in. A double layer main heat shield uses a silver outer face to reflect exhaust heat and a black inner face to absorb residual heat, with an insulating air gap between layers. A secondary double layer shield protects the inlet side from heat soak, while a dedicated carbon shroud blocks convective heat around the filter. Up front, a carbon scoop sits behind the grille and channels fresh ambient air through the OEM ducting directly to the intake area to keep IAT stable in real driving conditions.
