Part Number: 05164BNOS

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.
