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, EFI Hi-Ram, Base Only, Multi-port, Aluminum, Natural, Rectangular Port, LS3, L76, L92, L99 Cylinder Head, Chevy, 6.0L, 6.2L, Each

Holley EFI LS Hi-Ram intake manifold bases are cost-effective alternatives to fabricated sheet metal for high performance applications where induction system height is not limited. Coupling these cast aluminum Hi-Rams with the high flowing LS-style cylinder heads has outstanding potential for N/A and forced induction applications at a budget-minded cost. These modular lower manifolds accept a wide range of carbureted and EFI tops, making them attractive to builders and fabricators as the perfect foundations for custom induction systems. Fuel rails are included and machined for -8 AN O-ring fittings with passages large enough to accommodate high fuel flows and dampen pressure pulsations in the fuel system. The aggressive, bold, race-bred styling of Holley GM LS modular Hi-Ram lower manifolds will make bad intentions clear for drag race, muscle car, marine, off-road, sand rails, pulling trucks, track, and street-rod applications.
