Get a common Filter Minder and put it on the preturbo side. I don't think there will be enough restriction to make a measurable amount in most vacuum gauges, unless it's really filthy. Any clean filter will flow all the air these engines need. K&N just happens to be a convinent source of filters that suit the many non-stock needs that most Fram, etc. don't make.
