Cold air intake systems are a huge waste of money. The stock intake system IS a cold air intake. That's why it's sitting on the fender. The flaw in the stock intake system is the pipe that goes between the throttle body and the MAF sensor. It's poorly shaped and allows for expansion. You want something that is smooth and rigid. You could probably fab something up at home depot using 3" PVC pipe. The hardest part is finding a way to connect your homemade tub to the throttle body and the MAF sensor.
