Throttle body spacers don't work because we use an open intake manifold design that uses Manifold Absolute Pressure (MAP) as opposed to Mass Air Flow (MAF) air metering to determine fuel trims.
The air coming through the TB and the spacer hits a big open space in our manifolds (the plenum or "Keg" area) and any increased velocity, twisting, spiraling, rifling, or whatever else the TB spacer manufacturer claims the spacer does gets nullified when it hits that large open space. Then the air stops and waits for the intake valve to open and load the combustion chamber with a charge of air and fuel.
+1 learned my mistake , hopefully people take my advise and listen

uhh, that's not entirely correct.

dodgeram07 is correct in that the TB only allows a metered amount of air thru and unless you're at wot, those "twister" ribs they put in won't even come into play, but it's the bottom end of the intake that really undoes all the "work" they do.
