... wow... there are grooves in the spacer... That should tell you something right there. It's disrupting a smooth flow of air into the intake manifold. Might not be much to notice since it's not much disruption to significantly slow down the air speed, but it's still disrupting a smooth flow of air. Anything that says it helps spin the air, is most likely bullsh!t. end of conversation.
if this is in response to what i posted above, that's why i said i believe it's all a gimick.
