NOS "Wet" Nitrous System including 90mm Plate for LS1/LS6/LS2/LS3 applications.

The use of nitrous oxide (N₂O) as a performance enhancement has been traced back to World War II, where it was employed to give Allied aircraft "emergency" boosts in both airspeed and altitude capabilities.  Nitrous Oxide Systems (NOS) has refined this technology into one of the most effective ways to gain horsepower in your street or race car. 

NOS's "dry" nitrous systems inject nitrous directly into the air intake and use the factory EFI system to provide the extra fuel necessary. All the required electronics are included to enable the OEM computer to compensate for the extra fuel requirement on demand. Jets are included that allow the user to adjust power outputs to match available traction. The system can be activated only at wide open throttle and comes with a safety shut-off in the event fuel pressure drops below what is required to maintain an adequate flow. Everything required for a complete installation is part of the kit.

NOS also offers "wet" nitrous kits that feature a spray bar plate that mounts between the throttle body and the intake plenum. These kits are easily installed and can be adjusted to produce from between 100 and 150 extra horsepower, with provided jets. Activation is through a microswitch that is throttle-activated. All necessary plumbing and hardware is included to make a complete system. A detailed instruction manual is also provided. This manual also serves as an excellent tuning guide.
