Features

Note for Australian and European Markets

Unless otherwise stated, this product may be engineered for use in Left-Hand Drive vehicles. Steering components, pedals, shifters, linkages, wing mirrors, instrument clusters, panhard rods/traction bars, drag links, brake boosters, brake or clutch lines, accelerator cables, heater cores, some master cylinders and adjacent parts can vary between LHD and RHD configurations. In some models compenents such as windscreen wiper arms, motors and linkages could differ in their size and orientation. Items such as floor mats & dash mats may have differences in their structure around the front row (or padding in different locations). In many cases items are identical depending on the design of the vehicle and part, but may have differing mounts, lengths or bolt patterns. Carefully review the product images and details to ensure suitability for your vehicle, or contact StreetFX support if you are unsure. Returns are not accepted for special order products.

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.

Please carefully review the description and specifications for details on inclusions or any variations.

Intake Manifolds, Gen III, Hemi Hi-Ram EFI, Multi-port, 105mm, Standard Deck, Aluminum, Satin Finish, Chrysler, Dodge, Jeep, 5.7L, 6.1L, 6.4L, Each

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
