A short ram isn't a waste of money when used w/heat shield and the resonator removed so you can get isolate the filter element from the rest of the engine and some air from outside the vehicle will get in and be directed towards the filter. If I had the $$ i'd go w/AEM cold air intake w/bypass valve, but im getting my short ram for $15 shipped and considering my stock intake box is basically jacked(rear ended truck w/flowmasters, exhaust tip went through my air box) it's a deal I couldn't pass up.
