1986-1995 Ford Mustang Trick Flow R-Series Intake Manifold - 90mm - 5.8
Allow your 1986-1995 Mustang 5.8 engine swap to breathe better with this black 90mm Trick Flow R-series intake manifold kit! When it comes to making horsepower, one size doesn’t fit all. That’s why Trick Flow Specialties offers several different manifold combinations for 351 Windsor Fords. These Trick Flow R-Series EFI Intake Manifolds for 5.8 engines are emissions-legal and can be used on pollution-controlled vehicles. This kit comes with the upper intake, lower intake, upper-to-lower intake hardware, and gasket.

Trick Flow Quality
Each intake 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, which is a common problem with Ford EFI engines. The castings are made from A319 aluminum, so they work well with nitrous and are designed to fit under most stock-height hoods. The "R" series manifold features a massive 90mm throttle opening and an RPM range of 3,000-7,750. The upper intake features a satin black finish, while the lower has a natural cast finish for a great-looking intake combo.

Intake Specs:
  • Large cross-section with 13.300 in. runners
  • Overall height to the upper manifold flange is 11.500 in.
  • Overall height to the lower manifold flange is 5.375 in.
  • 2.000 in. x 1.200 in. port size at head
  • 2.380 in. x 1.380 in. port size at mating flange
