The Banks Power 42155-D Ram-Air Intake System with Dry Filter for your 03-07 Ford 6.0L Powerstroke outperforms the rest and flows up to 38% better than stock! The system's dome-shaped dry synthetic filter flows more freely than the factory's highly dense paper filter, and the contoured, aerodynamic shape eliminates restrictive sharp bends and chokepoints. Designed to work seamlessly with stock sensors and not generate trouble codes. Utilizes factory bellows to accommodate engine movement for greater durability. Easy install; the reusable filter is easy to access for monitoring and cleaning. (Unlike the stock filter, which is difficult to access ... not reusable ... and when dirty, requires replacement of the whole expensive unit!)

The only difference in the dry and oiled filter types is the oiled filter requires an oil for proper filtration while the dry filter does not require any type of oil.
