are you talking about spraying the radiator with it? i would start with the thermostat and fans first and see if you still need it, also a scoop really does help, my roomate has a vented hood on his 240, that thing never got up past like 170 degrees. only thing with the thermostat is in the winter time you may need dsmlink or some tuning software to get your car into closed loop.
