Designed to fit stock 5.0 Coyote heads found on 2011 to 2023 Ford vehicles - Holley's Hi-Ram and Ultra Lo-Ram intake manifolds are high-performance intakes that won't break the bank. They also fit other related engines, like the Voodoo and Predator. These manifolds are made of cast aluminum, built tough, and can handle all the boost you can throw at them. And because they're modular, you can easily access the runners to port them if you want to make more power. The port design has been refined with streamlined injector bosses to reduce turbulence without losing flow area.
