302 "R" W/90MM Opening Ford: 5.0L, 2,500 to 7,250 rpm range, R-series manifold with 90 mm silver powdercoated upper
Trick Flow has taken its computer-modeled Ford EFI intakes and enlarged the uppers to 90 mm to feed your engine with even more power-building airflow. Designed to boost high-rpm horsepower, this manifold features carefully designed runner lengths and cross sectional tapers to further promote optimum airflow. In addition, the specially engineered runners prevent air starvation of the front cylinder, a common problem with Ford EFI engines. This manifold has a silver powdercoat finish for good looks.
