This dry direct-port nitrous system drops into the Holley Hi-Ram intake via a pre-assembled plenum plate that mounts between the upper and lower manifold halves - no custom plumbing needed. Nitrous is delivered from the runner side directly above each cylinder for even distribution, using billet aluminum NX dry nozzles and two .093 Lightning solenoids. As a dry system it relies on the engine management to add the supporting fuel. Jetting is included for 50-300 HP, and this configuration ships with a 5 lb bottle and Lightning 500 valve.
