Cold Air Intake System Ver1 for BMW B58 G20 340i (MAF sensor)

Eventuri carbon intake for BMW G20 M340i B58 (before November 2018) — is a highly effective solution for improving airflow and reducing temperatures in the intake tract for models with a MAF sensor. Designed specifically for B58 turbocharged engines, this intake replaces the standard air intake system, which restricts flow and is prone to overheating due to its close proximity to the exhaust manifold.

The main stock problems are — air overheating and a restricted air channel. Eventuri solves these limitations thanks to a fully sealed carbon fiber housing with a dual cold air supply: one through the standard channel, the other through an opening in the wheel arch, which significantly improves air delivery to the turbo.

The carbon tube has an increased diameter (up to 111 mm) and a smooth taper, which creates optimal flow without turbulence. The kit uses its own dry air filter, which has been ISO tested for filtration efficiency.

Features:

• Compatible with BMW G20 M340i up to 11/2018 with MAF sensor

• Fully sealed carbon fiber construction

• Dual cold air supply (including supply from the wheel arch)

• High-performance filter with increased filtration area

• Gold heat shield insulation against radiant heat

• Precision machined mount for mass airflow sensor

• Optimized for maximum flow and stable boost pressure

Eventuri uses a patented intake housing geometry that creates the Venturi effect, maintaining laminar airflow and minimizing turbo resistance. This is not just tuning — it's an engineered solution that genuinely improves performance.
