just got it in today. normally, this kit would have nozzles that go under the fuel injector. i got their LS intake that has the ports drilled into the intake for the nitrous and fuel.
here's a close up of where the nitrous lines will go to just like if you had a nozzle.
here's what it looks like inside the injector hole where the nitrous and fuel will come out
the underside of the intake has a 1/4" thick aluminum plate
inside the intake
the NXL direct port kit replaces the factory LS intake fuel rails. this way, it pulls fuel right off the rails
the fuel accumulator. this helps with the initial hit of the system.
