Eventuri BMW B58 Carbon Performance Intake for M140i, M240i, 340i, 340ix, M340i, M340ix, 440i, M440i, M440ix
The Eventuri BMW B58 Carbon Performance Intake is the ultimate cold air intake and induction kit upgrade for the BMW B58 engine. Transform throttle response and drivability with a proven performance increase of 12 to 15 hp and 14 to 18 ft-lb. Designed specifically for the BMW M140i, M240i, 340i and 340ix, M340i and M340ix, 440i, M440i and M440ix platforms, this carbon fibre intake improves airflow, reduces intake temperatures and delivers repeatable gains on road and track.
Engineered around Eventuri’s patent pending carbon fibre housing and Venturi design, this B58 intake provides an aerodynamically efficient, laminar flow path from the high flow filter to the turbo inlet. The system combines an open filter enclosure with a dedicated carbon fibre scoop and comprehensive double-layer heat shielding to saturate the intake with cold air while resisting engine bay heat. It sets a new benchmark in quality, fit and finish for BMW B58 tuning and intake upgrades.
Why choose the Eventuri B58 intake
- Real gains: 12 to 15 hp and 14 to 18 ft-lb with stronger mid-range and improved response
- Patent pending carbon fibre Venturi housing for smooth, high-velocity, laminar airflow
- Carbon fibre scoop positioned behind the kidney grilles to maximise cold air feed
- Double-layer heat shields with silver and black layers to manage radiant and conductive heat
- MAF-integrated carbon housing and inlet tube for minimal turbulence and pressure drop
- Premium materials and craftsmanship throughout for OEM-plus fit and finish
Key components included
- Prepreg carbon fibre filter housing with integrated MAF tube
- High flow double cone air filter
- Aluminium cowl for smooth airflow entry
- Prepreg carbon fibre front scoop
- Prepreg carbon fibre filter shroud
- CNC machined MAF boss
- Double-layer main heat shield
- Double-layer secondary heat shield
- Laser cut mounting brackets
How it works
The reverse-mounted high flow filter is shrouded by a carbon fibre pod that smoothly reduces cross-sectional area into the integrated MAF tube, invoking the Venturi effect to accelerate airflow while maintaining laminar conditions. Reduced restriction lowers turbo effort and intake air temperatures stay low thanks to the carbon scoop channelling fresh air from the grille and the multi-layer heat shields isolating the intake from exhaust manifold heat. The result is sharper throttle response, stronger pull through the rev range and consistent performance.

Performance you can feel
Eventuri’s testing on a standard B58 showed clear gains versus the stock airbox across much of the rev range, translating to crisper part-throttle response and stronger acceleration. On-road airflow through the scoop further supports performance at higher rpm. This is a proven BMW B58 intake upgrade for enthusiasts seeking power, response and sound from a premium carbon fibre induction kit.
