Carbon fibre induction kit for BMW B58 turbo models: M140i, M240i, M340i
Unlock real-world performance from your B58 with this Eventuri carbon fibre induction system. Designed to improve engine breathing and reduce charge temperatures, this premium air intake delivers sharper throttle response, quicker turbo spool and a deeper, more purposeful intake note. Independent testing on stock B58 cars shows typical gains of 12 to 15 bhp and 14 to 18 ft lb, with stronger midrange and punchier acceleration right through the revs.
We run this setup on our own builds and our customers love it for its build quality, consistent intake temps and OEM-plus fit and finish. If you are shopping for a cold air intake for M140i, M240i or M340i, this is the benchmark upgrade for the BMW B58 platform.
Why upgrade your B58 air intake
- Proven power and torque gains on the 3.0 turbo straight-six
- Smoother, less restrictive airflow path for the turbo
- Lower intake air temperatures thanks to an efficient air guide and thermal barriers
- Enhanced induction sound without drone
- Direct bolt-on fit with factory mounting points and sensor location
Engineered for airflow and temperature control
This system replaces the restrictive factory airbox with a carbon fibre housing that integrates the MAF tube for a continuous, smooth transition from filter to compressor inlet. The internal profile is shaped to accelerate airflow while keeping it stable, helping the turbo work with less effort. A carbon air guide at the grille feeds fresh ambient air directly to the filter area, while multi-layer heat shielding creates a cool zone around the intake to combat engine bay heat soak.
What is included
- Pre-preg carbon fibre filter housing with integrated MAF tube
- High-flow double cone performance air filter
- Aluminium cowl for smooth entry into the filter
- Pre-preg carbon fibre front scoop to channel cold air from the grille
- Pre-preg carbon fibre shroud surrounding the filter area
- CNC machined MAF boss for accurate sensor placement
- Two-stage primary heat shield with reflective outer layer
- Secondary thermal shield protecting the turbo inlet region
- Laser-cut mounting brackets and hardware
