If so then your version of this should work much better than the drawing I saw above of the AFE air feeds.
Yes correct, the other Afe version that attaches a snorkel to each inlet port at the front of the car would actually flow less than stock whereas my setup will flow more. My cowl inlet/elbow which was a 2.5" round silicone is enough flow for 1 of the turbos. My setup had 16.5 sq/in of flow area
