Wagner Tuning Cast Aluminum Intake Manifold Kit – 2020+ Toyota GR Supra A90 (B58/S58 Compatibility)

The Wagner Tuning Cast Aluminum Intake Manifold Kit for the 2020+ Toyota GR Supra A90 is built for high-power B58 applications that push well beyond the limits of the factory plastic intake manifold. Designed to handle extreme boost pressure, elevated temperatures, and the airflow demands of serious turbo upgrades, this manifold provides a major durability and performance increase for modified Supra builds.

The OEM B58 intake manifold is constructed from plastic and was never designed for the sustained high boost levels seen in tuned or big-turbo setups. Under heavy load, the factory manifold can warp, leak, or fail entirely. Wagner replaces this weak point with a motorsport-grade cast aluminum manifold, engineered for absolute structural integrity and improved internal flow characteristics.

The manifold is manufactured using a high-pressure casting process that ensures consistent wall thickness and excellent strength-to-weight balance. Internal runners are CFD-optimized to promote smooth, even airflow distribution across all cylinders—an important factor for combustion stability and tuning safety at elevated power levels. The improved flow profile reduces turbulence, increases volumetric efficiency, and helps unlock additional power potential on both stock and upgraded turbo configurations.

Wagner designed this manifold to support both B58 and S58 layouts, offering additional flexibility for custom or hybrid engine applications. The robust aluminum construction resists deformation and heat cycling, making it ideal for Supra owners running E30/E50/E85, upgraded turbos, track use, or extended high-load pulls.

The kit includes all required hardware, seals, mounting points, and fittings to ensure correct integration with the Supra’s factory systems. Designed to be a drop-in replacement, it installs using OEM mounting locations without requiring fabrication.
