    I have K&N and they drip a bit under WOT. I am thinking of the old Moroso style . I went with the K&N for a the looks but I think I should have known better.I have PCV hooked up as the factory did . Any other options you guys have found??? Appreciate the input.

    They really shouldn't drip at all unless you have excess blow by. The only thing I could suggest is building a baffle inside the valve cover. I use the cheap Summit breathers.

    As suggested above use a baffle. I use the K&N filter but use a baffled grommet. I use the jegs branded one, there are 2 thicknesses, one for steel and one for aluminum.
