Many 7.3 owners go with the 6637 filter for the price, simplicity, and single hose clamp design as opposed to the split filter design of a stock airbox which can have a higher chance of dirt infilitration. Although not a 'cold air' intake, many still go with it. All you really need the filter and a stub of 4" exhuast piping to connect the filter to the existing intake after the old filter setup is removed.
