Hi Bobby,

18 sq in is a bit smaller than what I have. Mine is 10 1/2" wide and averages 2 1/2" high. However, I also use it to feed my engine intake which is a hole off to one side and right in front of the core where the high pressure area builds up. Here are a couple of photos of openings.

Ed,

Using your oil cooler scoop / duct what is the approximate size of the opening? I show the stock oil cooler being 18" x 5". 20% would be 18 sq. in.
