Description

This NOS Plate Wet Nitrous System from Holley is designed for LS-based engines with 90mm or 92mm 4-bolt cable-operated throttle bodies. It's a 'wet' system, introducing both nitrous oxide and fuel, capable of adding up to 250 rear-wheel horsepower without requiring injector upgrades (assuming adequate fuel delivery). The kit includes a ½” billet aluminum plate that installs between the throttle body and manifold, a 10 lb. NOS Blue nitrous bottle with brackets, and jet sizes for 100, 125, and 150 HP increases. Ideal for use with Holley Hi-Ram and MSD Atomic LS Manifolds.
