Holley High Ram Plate Direct Port Dry Nitrous System 12 LB Nitrous Express NX 20963-12

Holley Hi-Ram Dry Direct Port Nitrous System, 12 lb

This system is sold with a pre-assembled plenum plate (no plumbing required).

This Holley Hi-Ram dry direct port system takes full advantage of the Holley Hi-Ram intake manifold. The plenum plate bolts directly between the upper and lower intake manifold, making for a quick and simple installation. This system injects nitrous directly over each cylinder from the side of the runner, offering the most precise distribution possible without sacrificing horsepower. The system includes billet and carbon fiber Lightning Series solenoids, stainless steel braided hoses, wiring, switches, and all necessary bolts, nuts, and connectors for installation. If you order your system with a nitrous bottle, we include the industry-exclusive billet Lightning 500 valve and stainless steel bottle brackets.

The NX Dry Direct Port system delivers nitrous directly to each cylinder through the billet aluminum plenum plate, using our high-flowing NX Dry Nozzles.

These systems are designed for use with an engine management system that can add nitrous enrichment through the engine's fuel system.

Includes jets for 50-300 hp.

Includes 2 0.093" NX Lightning solenoids, WOT switch, stainless bottle brackets, 6AN nitrous feed line, relay, relay harness, and all hardware necessary to complete the installation.
