that's a really, really bad idea. i hope you're not serious. if you leave the filter off expect to be buying a new engine soon. anything that gets into your fender well, dirt, pebbles, etc. is getting sucked into your engine.unless you play stupid like i currently have and go a str8 air intake, just the tube, no filter, lol
and in minus 30 celsius, my car runs "like a rock!"
