What the -N- Tercooler does is spray nitrous onto a intercooler or I suppose a radiator. It's good for the intercooler because that sends super cool air to the Turbo to give it an extra horsepower kick. The radiator has nothing to do with the air Intake of the car, therefore it would not increase Performance what-so-ever. Don't buy it if you don't have a Turbo, waste of money.
Toss the Ntercooler, instead get a fogger nozzle. plumb it into your Intake, add a fuel solenoid, and all the hoses to connect that too.
instead of venting nitrous into the atmosphere to cool your radiator, shoot it down the Intake, that will make power.
Even if you did have a Turbo, I still wouldn't use nitrous in the N-tercooler, it's cheaper, and just as effective, to use CO2 to cool the intercooler instead, save the nitrous for spraying inside the motor (filling nitrous bottles isn't cheap!)
