VCTR Performance BMW M340i G20 / Toyota Supra A90 B58 Gen2 Intake Manifold

Overview

The B58 Gen2 factory intake manifold limits airflow at higher power levels and uses plastic end tanks that are vulnerable to pressure under elevated boost. This CNC billet aluminium manifold replaces the factory unit with improved end tanks and better flow geometry for high-output B58 Gen2 builds.

Why Upgrade?

• CNC billet aluminium end tanks — more pressure-resistant than factory plastic
• Improved flow geometry for high-power B58 Gen2 applications
• Compatible with 48V mild hybrid B58 Gen2 applications
• Direct replacement for the factory intake manifold

Engineering Focus

CNC billet end tanks replace the factory plastic units — a known weakness on heavily tuned B58 builds. The manifold supports improved airflow and is compatible with both standard and 48V mild hybrid B58 Gen2 configurations.
