(keyword: manifolds)Vehicle Compatibility and Return Conditions.
This item was designed and engineered in the USA for US domestic vehicles. OBD tools, ECUs, dongles, programmers, and tuners may have limited compatibility with vehicles outside the USA due to regional differences in emission standards and system configurations. Some features and functionality may vary depending on the vehicle and location.
Some electronic tuning devices and programmers require activation, registration, or pairing with a specific vehicle’s VIN (Vehicle Identification Number). Once activated or paired, these devices may become permanently associated with that vehicle, restricting or preventing their use on another vehicle, resticting our ability to offer returns or exchanges.
Please review the product details and images to ensure it meets your needs. For clarification or assistance, feel free to contact a StreetFX agent. Note: Returns are not accepted for special order or tuning products unless the unit is deemed faulty.
Images are supplied by the manufacturer and may be generic. While all efforts are made to provide accurate pictures, there may be differences in the actual product, such as colour, quantity, version, or included components. Please carefully review the description and specifications for details on inclusions or any variations. Some items may be sold individually or in sets, and images may occasionally depict additional products or quantities not included in your purchase.

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
