The Eventuri Black Carbon Intake System for the Toyota A90 Supra and BMW G29 Z4 M40i has been engineered to provide the turbocharger with a less restrictive airflow path while maintaining low inlet temperatures. Designed specifically for the B58 engine platform, this system addresses the critical relationship between heat management and intake volume required for consistent turbocharged performance.

Within the Supra engine bay, the intake system is positioned close to the exhaust manifold, an area highly susceptible to heat soak. Elevated temperatures reduce air density and force the turbo to work harder to generate boost. To combat this, Eventuri developed a fully sealed carbon fiber airbox which shields incoming air from engine bay heat while maximizing internal volume for improved flow characteristics.

During development, Eventuri engineers identified an additional opening toward the wheel arch and incorporated a secondary air feed into the airbox. This dual-feed configuration increases the availability of cooler ambient air without sacrificing the benefits of a sealed system. An integrated heat shield with gold reflective backing further minimizes radiant heat transfer from the exhaust side of the engine bay.

The restrictive factory intake tube is replaced with a smooth, high-volume carbon fiber inlet featuring a 111mm internal diameter that gradually tapers to match the turbo inlet. This continuous path helps reduce turbulence and improves overall turbo efficiency. The system is paired with a bespoke high-flow dry cone filter, ISO-tested for filtration performance and offering a larger surface area than the OEM filter.

Constructed from prepreg carbon fiber and finished to Eventuri’s exacting standards, this intake system delivers measurable performance benefits while providing a premium visual enhancement for the B58 engine bay.
