One more thought about air foils
This is looking down the air horn off my ZR-1. If you are unfamiliar, it bolts to the front of the throttle body on the LT5 motor. Notice anything in between the main throttle bores? Yea. Chevy must've thought it was worthwhile, also.
Why do I care? Well, I had an L98 for eight years, and now have an LT1 in an Impala. That airfoil gets around!
Airflow is what it is all about.

Probably more than a year ago, a forum member bought some dyno time and tested his vette with and without the air foil. I remember that it only made a difference at the very top of his rpm range and it added 3 hp and 8 ft-lbs of torque. Anything in the air intake circuit that reduces turbulance and friction will provide a higher, however small, density of air to the engine and hp is directly proportional to air density. Why there is so much discussion about that piece of metal is way way beyond me!

And on mine the valve cover breather hose that attaches on the pass. side goes to a port that comes out in the middle section you are showing in the picture. When a air foil is installed it is blocking air flow, not to mention the wedge holder that the air flow screws too, is restricting flow as well. This normally, may or may not be a problem, but believe me, when you start getting some blow by on the motor, it is.

BTW, I was given one, so I just put it on my car yesterday. Not expecting any SOTP impact but $ per HP should be good!
