Since everyone else has made it clear what a bad idea this is, let me ask why would you want to do this?
If you're thinking it will cool the intake air, you're right. It will slightly cool the intake air for about the first 1 second of operation, after which it will have all evaporated (it most likely will not catch on fire; after all, starting ether is much more flammable).
Most people who try to come up with cobbled-together 'improvements' to their intake systems don't seem to realize that a typical stree car engine needs anywhere from 300-600 CUBIC FEET of incoming air every minute.
