Product Description

The Nitrous Express 20931-10 is a purpose-built wet plate nitrous system engineered specifically for the 5th Generation Camaro LS3 throttle body. Unlike conventional plate systems that require the throttle body to be rotated 180 degrees - causing power loss, engine cover modifications, and wiring extensions - this system uses an ultra-thin billet aluminum plate that bolts directly between the throttle body and intake manifold in the factory orientation. The integrated Lightning Series solenoids keep the install clean and compact, while Phase 3 Spraybarless technology ensures precise, even distribution of nitrous and fuel for consistent power across all cylinders.

This kit delivers 35 to 150 wheel horsepower at the included jet levels and can be upgraded to 200-250 HP with optional jets. The included TPS Autolearn WOT switch activates the system only at wide open throttle and shuts off instantly on throttle lift, keeping the engine protected. Everything needed for a complete bolt-on installation is included, making this an ideal choice for Camaro SS and LS3 Corvette C6 owners looking for a reliable, high-performing nitrous solution straight out of the box.
