Product Description

Finally an alternative to the factory long runner intake manifold. Available for carbureted or fuel injected applications this intake is ideal for use in hi-performance Mustangs or street rods.

The intake is designed for optimum use in the 2500 to 7500 RPM range. It features plenty of material for porting for very high horsepower applications. These hi-flow intakes work well for forced induction applications.

The plenum dividers were designed to balance airflow into the runners for equal airflow to each runner. The intake is compatible with 99-up DOHC cylinder heads and can be used with any square bore carburetor or throttle body using the standard Holley 4150© Carburetor mount.



  • Utilizes standard Holley© bolt pattern for the carburetor.
  • Large boss cast into the bottom of the plenum to allow for any vacuum configuration.
  • Nitrous bosses cast into the bottom of each runner to allow for port nitrous systems.
  • Generous amount of material to allow for port 
  • This intake does not include provision for EGR. 
    If EGR is necessary it will require the use of a plate type EGR adapter if not using our plenum adapter.
