hey whats going on.. i just got the zex dry kit and put it in my civic... i did everything by the instructions and now am having problems... i took it for a run and didnt feel any increase of power.. then i parked it and turned the key off with the activation switch still ON and i heard the nitrous then.. whats going on?? seems like it is sprayin when the car is off not on.. wtf? also after the run the intake was cold as shit almost frozen

 

how far are you spraying down the intake pipe? take the hose out of the intake pipe and hit the button and see if it sprays. make sure it dosent spray when your car is off or you could blow it up.

 

Sounds like whoever installed it didn't know what the hell they were doing.
Find the person who did it and beat them severely, then take your car to a shop and have them fix it, or track down the problem yourself.
