I have a very well put together nitrous setup. It started out as a nitrous express universal efi wet kit and now has nearly every accessory you can get for it. The bottle is painted black to look great and its a HUGE 15LB bottle not one of those tiny 10lb ones so you get to use it a lot between fillups. Its got a electronic activation switch that ties into your cars computer to activate it. It has a bottle warmer to keep the bottle at optimum pressure for you to run consistent times. Its got Billet aluminum brackets that look great instead of the flimsy ones included with all the other kits. Its got a Shark 2 nozzle with jets ranging from 35hp to 175hp. Its got a pressure gauge on there so you know how much is included. Its even got a Air to Fuel ratio gauge so you can monitor your car to make sure it doesn't go lean during spray time. It will fit on any efi car.I am looking to get 550 OR BEST OFFER Please call or text me at 480-522-7781.
