The Nitrous Express Holley Hi-Ram plenum nitrous plate bolts between the upper and lower intake manifold on Holley Hi-Ram setups for a quick, clean install. Nitrous and fuel inject from the runner side to provide direct-port-like distribution without a flow-restricting nozzle or spray bar. Standard single-stage jetting covers 50–500 WHP. The billet plate has machined passages and systems include billet and carbon-fiber solenoids, stainless braided lines, wiring and all required hardware.
