Not much since your sucking in hot air right by the engine. FWI is the way to go. When i made my own FWI i just used dryer duct which worked perfect and had to roll the cut out open a slight bit more to fit it in. Just stuck the filter in after pulling off the wheel and removing the spash guards in the wheel well. Then it broke. lol
