Flow Up To 400 HP. This throttle body plate system comes ready to deliver 50-200 HP out of the box and is capable of flowing up to 400 HP with additional jetting. Featuring high-flow solenoids and a billet aluminum nitrous plate, this system delivers reliable performance for a wide range of horsepower applications.

Superior Atomization. The billet aluminum nitrous spacer plate features specially designed nitrous and fuel discharge ports that distribute a finely atomized mixture throughout the intake air stream. This design promotes even cylinder-to-cylinder distribution for consistent performance.

Intake Specific Design. Engineered specifically for GM Holley Hi-Ram intakes equipped with a 90mm throttle body, this system features application-specific solenoid brackets, pre-bent stainless steel hard lines, and mounting hardware for a precise fit and clean installation.

Hard-Line Plumbing. Pre-fabricated stainless steel hard lines connect the nitrous and fuel solenoids directly to the throttle body plate, eliminating traditional braided lines for a cleaner, more professional appearance under the hood.

Complete System. Includes the billet aluminum nitrous plate, high-flow solenoids, pre-bent hard lines, 50-200 HP jetting, electrical components, brackets, gaskets, and installation hardware needed for a single-stage wet nitrous setup. Fuel supply components are sold separately.

Wide Open Throttle Activation. Includes a wide open throttle (WOT) switch that allows nitrous activation only at full throttle, helping prevent unintended activation and potential engine damage.

Application. Specifically designed for GM Holley Hi-Ram intake manifolds equipped with a 90mm throttle body. Compatible with gasoline and E85 applications operating at 5-55 PSI fuel pressure with appropriate jetting.
