Description

Holley EFI Gen III Hemi Hi-Ram intake manifolds are for high performance applications where induction system height is not limited. Able to add even more power to your engine, these manifolds have large intake ports and a modular base design with runner lengths and tapered cross-sections that will perform well for a wide range of engine configurations. Their aggressive, bold, race-bred styling will make bad intentions clear for drag race, muscle car, marine, off-road, sandrails, pulling trucks, track, and street-rod applications. Holley EFI Gen III Hemi Hi-Ram intake manifolds feature cast aluminum construction offered with a natural satin or black finish. They are available with either a 95 or 105mm LS-style throttle body or as the manifold base alone for custom induction systems.

Features and benefits:

* Modular design base accepts a wide range of EFI tops and can be used as the foundation for custom induction systems
* EFI fuel rails are machined for -8 AN O-ring fittings with passages large enough to accommodate high fuel flow and dampen pressure pulsations in the fuel system
* Intended for use on naturally aspirated, forced induction, or nitrous engines in the 5.7L to 7.2+L range, and maximum power at 7,500 to 8,500 rpm
* Works with Gen III Hemi injectors and Bosch EV-1 style injectors
* O-ring seal to head offer superior OE-style sealing and are easy to replace
* Billet oil fill cap offers an attractive low-profile design
* Positive Crankcase Ventilation (PCV) ports with adapter fittings
* Port for OE-style Manifold Absolute Pressure (MAP) sensor (1 or 2 Bar)
* Cast-in pads for adding nitrous nozzles
