Would anyone like to hazard an enlightened guess as to the degree of air flow restriction of the OEM gauze or paper elements.K+N claim a 2% restriction and having just tried them on my '70 T120 i was very pleased and surprised with the noticeable power increase.And no the old paper ones weren't DIRTY!!
