Has anyone done any testing on the different vent kits? what I had in mind was similar to the Fram air filter test displays where there is a fan blowing air through a section of filter media and you can change that for a fram or several other aftermarket filter media types and depending on the amount it lifts the ball you can see the different levels or air flow resistance or backpressure. Anyone heard of this kind of testing being done?
