Default What sprays colder, NO2 or CO2?
I have a old ZEX 10lb bottle lying around, and I was thinking of picking up a intercooler spray bar kit for my front mount and running that to help intake temps. Anyone got any ideas which one has the lower spray temp?

CO2 should be better since it has a ~30% higher latent heat of vaporization.

Spray temperature will be significantly lower for CO2. CO2 should spray at around -110 F and NO2 should only spray at around 70 F.

Just make sure you don't have your Air intake near the radiator or close to the spray bar!

Nothing like a little natural asphyxiation
