Wagner Tuning EVO1 Intake Manifold with Integrated Intercooler – 2020+ Toyota GR Supra A90 (B58)

The Wagner Tuning EVO1 Intake Manifold with Integrated Intercooler for the 2020+ Toyota GR Supra A90 is one of the most advanced charge-air cooling solutions available for the B58 platform. Designed for high-power and high-heat applications, this assembly replaces the factory plastic intake manifold with a motorsport-grade unit that dramatically increases cooling efficiency, reduces intake temperatures, and stabilizes performance under extreme load.

Unlike the OEM manifold—which incorporates a compact, efficiency-limited water-to-air intercooler—Wagner’s EVO1 system integrates a massively larger, high-density charge-air cooler directly into a cast aluminum manifold housing. This significantly increases cooling surface area, improves heat dissipation, and delivers drastically lower IATs even during repeated wide-open throttle pulls, elevated boost, or ethanol-based tuning.

The integrated intercooler core uses a motorsport-proven bar-and-plate design optimized through CFD and flowbench testing. High-volume end tanks ensure uniform air distribution across all cylinders, eliminating the airflow imbalance and hotspot issues sometimes seen in the factory B58 charge-cooling system. The result is smoother combustion, improved tuning headroom, and safer, more reliable power delivery at elevated power levels.

Constructed from cast aluminum, the EVO1 manifold offers tremendous heat resistance and structural strength compared to the factory plastic manifold. Under high boost pressures—especially with upgraded turbos or fully built engines—the OEM manifold can deform or fail. The Wagner EVO1 eliminates these risks entirely.

The integrated intercooler core interfaces directly with the Supra’s factory water-cooling system, while offering improved coolant flow and reduced pressure drop. When paired with an upgraded heat exchanger or auxiliary radiator, the EVO1 becomes one of the most robust charge-air cooling systems available for the platform.
