Finally, an affordable Coyote intake manifold that also performs! The Hi-Ram and Ultra Lo-Ram are designed to fit stock bolt pattern OE heads found on the 2011-2023 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, both manifolds have a 9.20-inch 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 2015-2023 Mustang factory hoods. Offered in both round and oval throttle body configurations, with replacement front inlets for easy interchangeability. The oval inlet can accommodate up to a 150x66mm single throttle body and 93mm on the round variant. Round inlets include standard mounting provisions for GT350, GT500, and LS 4-bolt throttle bodies. 2011-2023 GT throttle bodies can be used with the optional 717-18 adaptor.

The aggressively designed Hi-Ram is constructed in a two-piece design to accommodate for air to water intercoolers and feature up to 20% more plenum volume versus Ultra Lo Rams. This manifold design is only offered in an oval throttle body configuration.
