If you are running one of the many LS based engines and would like to add up to 250 additional horsepower, NOS has a complete nitrous kit option for you.

These kits are ideal for adding a little more power to that stock engine or a lot more power to that custom built Hot Rod. Available for 4-bolt, drive-by-wire or cable operated throttle bodies in 90mm, 92mm, 102mm & 105mm plate sizes. These are Wet plates, meaning the additional fuel is added though the nitrous system, so there are no requirements for an injector upgrade*.

*It is important to ensure the existing fuel delivery system is adequate to support the expected power levels.

Features:

  • Fits 90mm or 92mm cable actuated throttle body
  • For use with drive-by-wire or cable operated Throttle Bodies
  • Single Â1/2” plate between the throttle body and manifold
  • Ideal for use with the Holley Hi-Ram & MSD Atomic LS Manifold
  • Supports up to 250 RWHP (Rear Wheel Horse Power)
  • Plate outlet design maximizes distribution
