SBC Intake Manifold Ri Series Single Plan

The SBC Intake Manifold Ri Series Single Plane from Trick Flow is purpose-built for small-block Chevrolet engines demanding maximum airflow and responsive throttle characteristics. This single-plane design is engineered for high-RPM performance applications, making it the ideal choice for street performance builds, bracket racing, and engine swaps where peak horsepower and torque in the upper RPM range are priorities. Whether you're upgrading a classic muscle car, a modern LS swap, or a dedicated race platform, this intake manifold delivers the flow characteristics necessary to support aggressive cam profiles and optimized fuel delivery systems.

Trick Flow's Ri Series single-plane design utilizes optimized runner geometry to minimize turbulence and promote laminar airflow through each cylinder port. The manifold's construction emphasizes high-velocity fuel atomization, critical for achieving complete combustion at elevated RPM levels where traditional dual-plane designs struggle to maintain consistent mixture distribution. At 17.88 pounds and measuring 14.85 x 9.7 x 24.3 inches, this manifold integrates seamlessly into modern engine bay layouts while maintaining the structural rigidity demanded by boost or nitrous applications. The single-plane architecture creates a dominant mid-to-high RPM powerband, making it especially effective with aftermarket carburetors, EFI systems, and tuned exhaust configurations.

This intake manifold performs best on engines running 5,500 RPM and above, making it unsuitable for low-RPM torque-focused builds but exceptional for dedicated performance platforms. Installation requires standard SBC head gasket compatibility and works with both carbureted and fuel-injected small-block Chevrolet configurations, provided your fuel system and tuning strategy are optimized for the manifold's peak powerband characteristics. Paired with a quality carburetor or EFI conversion, high-flow cylinder heads, and a cam profile designed for upper-RPM operation, the Trick Flow Ri Series single-plane manifold unlocks the breathing potential that serious enthusiasts expect from competition-grade engine modifications.
