F3 Grill Filter

[PW2013STL]

After spending 5 hours cleaning the gunk out of both radiators I added a screen and filter behind the grill. I was concerned that would create an air flow issue resulting in overheating. I chose thin floor duck filters to minimize the restrictive media.
I can report that after 2300 miles on our Black Hills/Badlands trip. that no issue with overheating and the Spyder only showed 4 bars on the gage the whole trip.

Here is what the filter looks like after trying to take out all the bugs in South Dakota.

I also am switching to a $.99 furnace filter that is less restrictive. Called big Blue Filter from Menards.
