NOS GM LS Wet Nitrous System

NOS has long been the trusted name in nitrous oxide performance, and their GM LS Wet Nitrous System line delivers that proven expertise in a complete, ready-to-install package. Designed specifically for GM LS-based engines, these kits are the ideal solution for enthusiasts looking to unlock serious additional horsepower — whether you're building a street-driven machine or a full-on custom Hot Rod.

What Makes It a "Wet" System?

These are wet plate kits, meaning the additional fuel required for the power increase is delivered through the nitrous system itself — not through the engine's existing fuel injectors. This self-contained fuel delivery approach means no injector upgrades are required in most applications, simplifying the installation process significantly. It is important to ensure your existing fuel delivery system is adequate to support the target power level.

Complete Kit — Everything You Need

Each NOS GM LS Wet Nitrous System ships as a comprehensive kit with all the components needed for installation. From the nitrous bottle and solenoids to the jetting, tubing, and wiring, NOS has taken the guesswork out of nitrous upgrades so you can focus on putting power to the pavement.

Spark Plug Recommendation: For best performance and engine safety, NOS recommends using one step colder spark plugs at lower power levels, and two steps colder spark plugs at higher power levels.

Racing use only. Not legal for use on emissions-controlled vehicles. Always verify your fuel delivery system is capable of supporting the selected power level before use.
