NOS Injector plates assure a steady, precise metered flow of nitrous and fuel for reliability backed with years of laboratory research as well as dyno and drag strip testing. NOS injector plates are available for those who want to build their own system or upgrade their current nitrous system without having to go through the expense of a new complete system. For instance, if you own a non-adjustable factory preset 125HP Power Shot kit and you wish to have the ability to jet for various power ranges from 75-175HP, you might opt for a Super Power Shot Injector Plate kit. Unless specified, NOS Injector plates incorporate a low profile (1/2" thick) design and are constructed of solid billet or die cast aluminium with a durable black finish. Included are all applicable gaskets, studs, jets and plumbing.
