I have the PSM, but you could make the same setup with a dryer vent hose and a hole through your firewall. Gets you cold cowl induction air. Gained 1mpg on the highway and dropped an easy 100 EGT across the board.

I've done the airbox mod already, but im looking for something that well help my truck breathe better and i want to protect my turbo from all the dirt/sand that floats around in the air out here.

Whats the trick to cleaning the dry filters that everyone makes now?

What makes you think the airbox/cowl induction is not breathing or filtering well?
