Thus, I am calling them out. I am hoping other potential buyers will do the same.

I agree 100% with the theory -- but I have yet to see clear evidence of it. Actually, I was surprised to see the panel filters plus smooth tubes making approximately equal gains.

Also, you keep making reference to the longer tubes as if the tubing length itself (rather than where it pulls air) is important -- it might be, but longer tubes tend to move peak torque down not up. Does that appear to occur with the longer tube intakes? Do they mainly gain in the midrange?

Again, I am looking for clear empirical evidence of performance differences -- how hard would it be to test?
