Air filter cleaner

I cleaned my f250 7.3 air filter. I got a K&n kit with spray and oil. The oil ones on after everything. Do I have to let the oil dry before I run it of is it ok if my motor sucks a little cleaner oil?

The oil never really dries, but it adheres to the filter element. It isn't a bad idea to let it sit, but doubt it is that big an issue if you don't. The idea of the K&N is a bit like the old oil bath filters, the dirt gets caught by the oil, not as much the screen itself.

K&N recommends to let the filter dry out before re-oiling so that the oil doesnt run from where its still damp. after oiling it says to let it sit for 20 mins so that the oil can soak in then recheck to re-apply for the areas that did not get coated..

some prefer the oil bottles that drizzle the oil i prefer the aerosol cans
