Product Overview

The Nitrous Express 78mm GM LS 3-Bolt Wet Nitrous Plate System adds 50-400 wheel horsepower through a CNC-machined, 3/4-inch-thick billet aluminum plate that installs between the throttle body and intake manifold. The plate introduces nitrous and fuel directly into the incoming air charge, providing clean distribution without requiring intake manifold modifications.
The system uses a 15300L Lightning Series nitrous solenoid and a 15201L Lightning Series fuel solenoid, with 18–20 Hz recommended for progressive operation. Included jetting delivers 50-400 additional horsepower at the wheels when operated at 1000 PSI bottle pressure and 55 PSI fuel pressure.
Made in the USA, this system is an ideal bolt-on solution for early LS cars, GM trucks, and LS swaps that utilize a compatible 78mm 3-bolt throttle-body intake.
