this weekend me and my friend Gary are gonna hook up Nitrous to my car. he has 2 kits and he wants to put one in my car for a little while. its not gonna be permenant. we are just gonna put it on and go to the track the following weekend. i think its a dry kit. with a 100 or 125 shot. not sure exactly. i just wanted to make sure there was nothing special we had to do to my car first to make sure it doesn't wreck anything. do i need to change the spark plugs or anything? is there any tips someone can give me that has installed it on a gen4? thanks guys.
