As an OEM, unmodified lid the air enters the unobstructed but restricted airway then follows the duct until it hits the filter where the air is filtered (so we hope). The filtered air then passes through and sucked into the engine to be mixed with fuel for combustion.
With an EHS model lid the above mentioned "unobstructed but restricted airway" is semi blocked with a porous foam material so air has to be pre-filtered through the OuterWear material and then hits the filter where the air is filtered (so we hope). The filtered air then passes through and sucked into the engine to be mixed with fuel for combustion.
So what is the downside to a EHS model lid, seems to me its a win win, more air that has been pre filtered by OuterWare material. I would rather pre filtered air vs direct air before it hit the air filter.
Am I on the right track or totally off the mark? :getrdone:
