dry is harder to install. wet just goes through the intake. for the dry, you have to drill the intake manifold and can be very costly if you dont know how to do it.
not quite, dry is when nitrous is sprayed in before the throttle body, while wet is then fuel and nitrous is sprayed at the same time. when you drill into the intake manifold, thats direct port nitrous (which is also wet b/c it sprays fuel too). NOS makes these coool nozzles that fit between the fuel injector in the intake manifold so u dont have to drill into the i/m anymore.
