Eventuri Black Carbon Intake System V2 – BMW B48 (G20 / G22 / G26 / G42)

OVERVIEW

The BMW G20 B48 Eventuri intake was developed to give the turbo a less restrictive flow path while keeping inlet temperatures low. In the G20 the intake sits next to the exhaust manifold, which rapidly heat soaks the engine bay, and a turbo forced to build boost with heated, less dense air gives up performance. The only way to keep IATs to a minimum is a fully sealed intake, which normally creates a restriction because there is just one factory air feed to draw from.

During development Eventuri found an additional opening into the wheel well area and took advantage of it by adding a secondary feed to the airbox. The sealed airbox also carries a gold reflective heat shield to minimize radiative heat transfer from the exhaust manifold, and internal volume was maximized with a recess left for potential strut braces. The convoluted stock intake tube is replaced by a smooth carbon tube of larger internal volume that tapers down to match the turbo inlet, and the system is finished with a custom high-flow dry filter that is ISO tested for filtration performance and has a larger filtration area than stock.

This V2 system is for B48 cars built after November 2018, which use a temperature sensor in the intake tube. It covers the G20 3 Series, G22 / G26 4 Series and G42 2 Series B48 models.

SPECS

• Intake tube internal diameter increased from 80.8 mm (3.2 in) stock to 109 mm (4.3 in) — an 82% increase in cross-sectional area over stock, per Eventuri
• 100% pre-preg carbon fiber with no fiberglass, for a smooth internal surface that maintains laminar airflow
• Gloss black carbon finish
• Fully sealed carbon fiber airbox with dual air feeds, including a secondary feed from the wheel well opening
• Airbox volume maximized with a recess for potential strut braces
• Bespoke high flow dry cone filter — ISO tested, cleanable and reusable, double-layered non-woven mesh on a urethane base with an internal flow-guiding cone, larger filtration area than stock
• Heat shield with gold reflective backing to combat radiant heat from the exhaust manifold
• CNC machined temperature sensor mount
