Nitrous Express Holley Hi-Ram Plenum Plate Conversion Kits

Not Yet Reviewed

Nitrous Express Holley Hi-Ram plenum plate conversion kits bolt between the upper and lower intake manifold on Holley Hi-Ram manifolds for a quick and clean install. Nitrous and fuel are injected into each cylinder from the side of the runner, providing direct port-like distribution without having a flow-restricting nozzle or spray bar in the runner. High-tech Holley Hi-Ram plenum plate conversions are made from billet aluminum with passages machined directly into the plate, so there's no need to worry about spray bars breaking or spinning.
