Now the issue will be how the air is delivered through the venturi as the OEM filter does not have the "Stinger".
That is the best part of the S&S I bet.
I wonder if someone could make a simple collar that could be placed on the throttle body opening with a few blades to create some swirl. Would be simple enough to machine.
The stinger shapes the air flow and not create turbulence or a swirling effect. If there is a swirl coming off that stinger I would love to see the wind tunnel testing showing it.
Years ago i saw the wind/liquid turbulence created by a round ball flying through the air. You would normally think it would be smooth, but it was not, it was very disturbed as the rear side of the ball was creating very uneven flow of air where the air tried to go behind the ball. Bullet shape and air flow are a real science and speed of the object going through the air or the speed of the air over an object dictates shape. I suspect S&S used a wind tunnel to test the shape of the stinger.
