Holley EFI Coyote Hi-Ram Intake Manifold Bases

Holley EFI Coyote Hi-Ram intake manifolds are available with the BASE ONLY, no top included, if desired. The aluminum bases are offered in a black or natural finish.

However, if you want the complete intake manifold system, here is the description:

Holley EFI Coyote Hi-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 finishes, the manifolds have a 9.20 in. runner length and are designed to improve the mid to high RPM powerband. The aggressively designed Hi-Ram is constructed in a two-piece design to accommodate for air to water intercoolers and feature up to 20 percent more plenum volume versus Ultra Lo Rams. This manifold design is only offered in an oval throttle body configuration.
