Hey guys i am going to be installing my NX GEN X2 System this weekend. I know that i need one range colder plugs. I need to know exactly what plugs to buy and what do i set them at. Also where could i get the plugs at a normal autoparts??? Also by the way, should i get a fuel pressure regulator, its a wet kit so i dunno if i need one or not. Oh and any other things you guys think that i should check or do before i run it... Thanks ALot
