no you shouldn't because the cold air that your engine sucks up can quit your engine and stop running
If you are asking if it will tear up engine then the answer is yes. As far as exploding not that I am aware of unless you feel a engine revving up so high on NOS (Nitrous Oxide Systems) or methanol that it throws a piston/rod through the engine. I have been told too much ethanol will break the fuel pump and I know if you put diesel in a gas engine it will foul out and quit. Now a methanol engine on a dragster can blow up if it breaks down during races so that part is true. It all comes down to what type of engine and what type of fuel you are talking about.
