I'm debating if I should re-oil my KN intake filter or simply wash it and reinstall dry. I would then place panty-hose or something similar on the outside of the filter. Anyone run the KN filter dry before? Does a dry filter still catch the small silty elements? The reason I ask is that when I rebuilt my engine I had both my upper and lower stock intake manifolds in the parts washer for three days to loosen up all the grimmy sludge built up inside. I don't want that sludge to come back.
