How well does the DRYFLOW filter flow?
We design our DRYFLOW filters to exceed the flow requirements for the size of the engine that we designed the intake for. For instance, the flow requirements of a 5.4L V8 engine with a volumetric efficiency of 80% is 460 cubic feet/minute (CFM) @ 6000 RPM. The DRYFLOW filter we supply for an engine this size flows nearly 1,100 CFM (a 4″ x 9″ filter), which accomplishes two things. The first is that it allows you to add modifications that increase flow demand without exceeding the flow capabilities of the filter, and it also extends the filter’s service cycle (you don’t have to clean it as often) because it can trap more dirt without sacrificing flow. Rest assured that we have taken flow into account for all of our intake designs and our DRYFLOW filters will deliver more than adequate flow for your vehicle.
