Wet Nitrous Plate Kit GM LS Drive-by-Wire Throttle Body 4-Bolt 102/105 mm 1997-2012 - Black, up to 250 HP

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.

Good to know

• Retains stock throttle body location and orientation using a 1/2" billet aluminum plate. Power levels up to 250 RWHP do not require injector upgrade, however, the total fuel supply system must be sized according to expected power levels. Recommend 1 step colder spark plug up to 150 RWHP, 2 steps colder spark plug on 200 and up RWHP

Important: this product runs on nitrous oxide (N2 PI), a gas we do not supply and which is currently difficult to obtain. It is your responsibility to find a local supplier of gas for professionals. NOS bottles do not comply with CE standards (they do not carry the PI mark): only CE-approved bottles may be used. European manufacturers offer bottles approved to contain this gas; please check the applicable standards and verify the manufacturer's origin and compliance before purchasing. NOS fittings are not metric (AN / NPT threads depending on the part numbe PI): plan for the adapters needed for your installation. Please comply with the regulations in force in your country.
