i just recently got a intake plenum spacer that is drilled for the nirous fogger nozzle to screw into. Do i need to get my car re tuned for the repostioning of the nozzle?
You screw the nitrous fogger nozzle into the spacer just like you would into the air intake. so yeah no rail or anything just a hole you screw the fogger nozzle into it.
To be honest with you I wouldn't do that if I was you, because you wont spray the nitrous in all cylinders equally. As a matter of fact you will only spray it in one port. This is how it should look. Notice the bar going across the port holes? That's for even distribution. If your spacer doesn't have that, than I wouldn't spray that car if I was you. You will do some damage.
