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.
(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. For assistance or clarification, please contact customer support.

Intake Manifolds, Holley EFI, Coyote Ultra Lo-Ram, Base Only, Throttle Body Injected, Standard Deck, Aluminum, Black Finish, Ford, 5.0L, Modular, Each
Holley EFI Coyote Ultra Lo-Ram intake manifolds are designed to fit stock bolt pattern OE heads found on the 2011-23 Ford 5.0 Coyotes and related engine families, such as Voodoo and Predators. These kits include fuel rails for use with OEM-type fuel injectors and clips, mounting hardware, and O-ring gaskets. Offered in black and natural as-cast finish, the manifolds have a 9.20 in. runner length and are designed to improve the mid to high RPM powerband.
The Ultra Lo-Ram provides an additional 19.4mm front and 42.6mm rear clearance compared to the Ford Performance Cobra Jet manifold—plus clears 2015-23 Mustang factory hoods. They're offered in both round and oval throttle body configurations, with replacement front inlets for easy interchangeability. The oval inlet can accommodate up to a 150 x 66mm single throttle body and 93mm on the round variant. Round inlets include standard mounting provisions for GT350, GT500, and LS 4-bolt throttle bodies. 2011-23 GT throttle bodies can be used with the optional 717-18 adapter.
(NOTE: Coyote Ultra Lo-Ram intake manifolds are available with the base only, no top included, if desired. See "Intake Section Included" tabs.)
