True Flow has added the Xtreme Duty Intake, or XDi line for heavily modified trucks with both diesel and gas engines.  Their past philosophy has always been to use as much of the stock system as possible to hold down cost while supplying enough air to allow for a medium level of modifications.  Now, they have decided to step into the extreme modification arena.  They are replacing the entire filter box as well as the intake tubing to allow for maximum air flow for heavily modified trucks.

True Flow will continue to use the same filter media, which supplies the cleanest air on the market with excellent life and flow characteristics.  They are releasing direct bolt on applications as well as some universal fit parts.  Especially for a Ford 6.0L, this will allow the great True Flow protection without having to fight the factory filter box!
