Exactly what it says, a 7.00 dryer duct from Home Depot. I cut a 4" diameter hole in my air silencer, attached one end of the duct to it and the other end into the fender and down to the fog light hole. Sucks more air from outside the engine compartment through a bigger hole than the stock air silencer tube. I did notice a SOTP increase in power. It's a cheap mod until I decide to spend the money for a Densecharger. From all I've read here on the site, it seems the way to go for a cold air system. But then again, there's always that beautiful Shaker intake. :grin:
