The Nitrous Express direct port nitrous plates are designed to fit factory modern Hemi Engines. This setup is capable of spraying anywhere from 100-400 horsepower. Direct port plates offer an advantage compared to a single nozzle or a throttle body plate, giving you the best distribution possible by feeding an equal amount of nitrous and fuel to each cylinder.The plates bolt under the intake manifold making installation quick and simple. The plates come in at 5/8" thick so there will be no need to run an aftermarket hood.
