Thanks! It's a wet kit, there are 2 solenoids, 1 fuel and the other nitrous. They both feed into a Y shaped nozzle that sits in the intake elbow on the throttle body. I didn't change the plugs, but I didn't have any issues with misfiring. I may change the plugs to a colder non-platinum plug, because I read that platinum plugs may react with the nitrous and foul out. If it runs a little funky I'll know where to look first I guess.
