My only concern is making it run too lean or rich. Was thinking rich since the overall filter surface area on the pre-filters is sort of small, as compared to how it could be with the longer K&N filters. Guess at this point it is just trial and error. I will oil up the filters, maybe put some nylons over them, and see how it runs.
Call UNI ask them how many CFM the stock main filter flows when you install a UNI then ask them how many CFM's the filters you used for the prefilters flows this will give you an idea if its going to be restrictive.
OR you can test it yourself if you can find the equipment needed you would check the negative pressure in the air box with the prefilters off like a long
WOT (Wide Open Throttle) run then install the filters and check the negative pressure in the box again see how much difference with the filters ideally you would want no increase or restriction.
You would want to know the usually in inches of water
