What is the difference between a wet and dry system?

 

wet is nitrous an fuel

dry is all nitrous


don't buy a dry kit

 

Not necessarily don't buy dry, just wet is easier and safer.

 

A wet kit introduces the fuel and nitrous through a nozzle in your intake tract.

A dry kit introduces the nitrous through a simpler nozzle however bumps up your fuel pressure in order to introduce the extra fuel required through your stock fuel injectors.

Go with a wet kit.

 

i have heard of people spraying there intake and/or intercooler with nitrous. is that safe?
