Holley EFI Coyote Ultra Lo-Ram Intake Manifolds

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.)
