- Description
The AMS Performance Intake Manifold for the 2020+ Toyota GR Supra A90 is engineered for high-power B58 builds that demand superior airflow, consistent cylinder fueling, and rock-solid reliability. As boost and horsepower levels rise, the factory plastic manifold becomes a critical bottleneck—both in flow capacity and structural integrity. AMS solves this by redesigning the manifold from the ground up using motorsport-grade materials and CFD-validated geometry.
Carved from high-strength billet aluminum, the AMS manifold delivers massively increased plenum volume, a more efficient air path, and balanced distribution across all six cylinders. This ensures each cylinder receives equal airflow under high boost—something the OEM unit struggles to maintain—resulting in smoother power delivery, improved safety on aggressive tunes, and the ability to support significantly higher horsepower levels.
A key feature of this system is its compatibility with port injection, giving tuners precise control over additional fueling when the factory direct-injection system approaches its limits. This makes the AMS manifold ideal for high-boost, ethanol, hybrid turbo, and full big-turbo Supra builds. Integrated fuel rail provisions, optimized injector angles, and a robust gasket interface ensure leak-free performance even under extreme operating pressures.
The upgraded design also improves thermal stability. The billet aluminum construction provides exceptional resistance to heat and pressure, eliminating the cracking or deformation that can occur with plastic manifolds at elevated boost levels. Whether you're pushing 500 whp on a hybrid turbo or building a 900+ whp monster, the AMS manifold provides the headroom and safety margin required to do it reliably.
From street cars to full track builds, every AMS component is tested under real-world abuse. The intake manifold is the result of thousands of engineering hours, flow bench analysis, and high-load dyno validation—ensuring it performs consistently under the harshest conditions.
