Box-R-Series EFI Intake Manifold

The Trick Flow Box-R-Series EFI Intake Manifold is engineered for Ford 5.0L (302-based) engines, specifically designed for non-EGR applications. This complete intake system, including both upper and lower sections, is constructed from aluminum and features multi-port fuel injection. It is optimized for a 3,000 to 8,000 RPM operating range, making it suitable for high-performance builds. Key specifications include a 90mm throttle body bore size and a 90mm engine block deck. The runner length measures 9.750 inches, with a port size at the head measuring 2.000 inches by 1.200 inches. The overall height to the upper manifold flange is 11.500 inches, and to the lower flange is 4.625 inches. This design is intended to fit under most stock-height hoods. This intake manifold is specifically designed for the 1987-1995 Ford Mustang GT models with the 5.0L/302 V8 engine. It is compatible with Trick Flow R-Series heads and requires an aftermarket fuel rail.
