On the Super Duties, the stock air box inlet is almost right up against the radiator support on the driver side. There is a plastic panel where it is. The ZooDad mod is when people cut a hole in the plastic panel right in front of the inlet. This creates a "Ram Air" affect and also gives it a cooler charge of air. I was considering this mod, but living in Colorado, with the snow and rain we have, i am worried about moisture getting into the air box and messing things up. I was hoping to hear from someone who has tried this here in Colorado and get their opinion on it.

Thanks for the help. I really appreciate it.

God bless,

Cory
