Trick Flow Box-R-Series Intake Manifold 351 Windsor

When it comes to making horsepower, one size doesn't fit all. That's why Trick Flow® designed their Box-R-Series intake manifold for Ford 351 Windsors. 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. Trick Flow® Box-R-Series manifold uppers are made from A319 aluminum and available in silver and black powdercoated, finishes for long-lasting good looks, or in a natural version for those who prefer a natural aluminum look or wish to use a custom finish.
