Cold Air Induction Scoop

Free horsepower is what you get when you rig up some household heater ducts and dryer hose feeding into a homemade two-snorkel air cleaner (made by sawing off the snorkel from one air cleaner and attaching it to another air cleaner with sheet-metal screws).  The air comes in on either side of the radiator.  The only drawback is that I have to dump the bugs out of the air cleaner every so often.
