R-Series EFI Intake Manifolds for 5.0L Ford :

When it comes to making horsepower, one size doesn’t fit all. That’s why we offer six different manifold combinations for 5.0L and 351W Fords. Each manifold is computer-engineered to deliver an excellent balance of airflow distribution and velocity to increase low-end torque and provide superior high-rpm horsepower. The design also prevents air starvation of the front cylinders, a common problem with Ford EFI engines.
