Ok… I’ll assume we’re talking about cooling the intake or IC.

There is a CO2 kit available to cool these items off.

If we’re talking about injection (which we aren’t) There are propane INJECTION kits, however I’ve only seen them available for diesel engines.

However, for gas powered cars, I have seen a few methanol injection kits that only work for those of us running 6-15psi, or 8-30psi.
