Nitrous Express Holley High Ram Plenum Nitrous Plate Kit w/o Bottle

These high tech nitrous plates 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. Systems come standard as a single stage with jetting for 50 to 500WHP. The plate is made from billet aluminum with passages machined directly into the plate so there is no need to worry about spray bars breaking or spinning. System comes complete with billet aluminum and carbon fiber Lightning Solenoids, stainless steel braided lines, wiring, switches and every nut, bolt and connector needed to install the system. Systems ordered with a nitrous bottle include the new billet aluminum Lightning 500 bottle valve and stainless bottle brackets.

Important Note Regarding Nitrous & Pressurised Systems

Orders containing nitrous systems or other pressurised canisters may require additional handling and inspection prior to dispatch.

Due to the nature of these products and applicable transport and state regulations, each system is individually inspected, released, and purged where required to ensure compliance with air and road freight standards. While most orders ship within our normal timeframes, this process may occasionally result in slightly longer dispatch times than those advertised.

We do everything we can to minimise delays, and the vast majority of shipments move through without issue. If you are working to a tight deadline or require urgent delivery, please contact us prior to placing your order so we can confirm the most suitable options.

We appreciate your understanding and patience - this process ensures safe, compliant transport and delivery of your order.

Images are supplied by the manufacturer and may be generic. While all efforts are made to provide accurate pictures, there may be differences in the actual product, such as colour, quantity, version, or included components. Please carefully review the description and specifications for details on inclusions or any variations. Some items may be sold individually or in sets, and images may occasionally depict additional products or quantities not included in your purchase.
