I also see, have pointed this out before, a conflict between the 2nd and 4th sentences. The second sentence says that velocity stacks, basically modified intakes on a carb to speed flow, are not legal. The last sentence says, or at least we all believe it to say, that everything in front of the carb is free so long as you don't use cowl induction, ram air (unless stock) and you pick up your air within the engine bay.
I think the intent of the "no velocity stacks" (which is defined I believe to include air horns) rule is to prohibit anything that eases or speeds up the flow of air into the carburetor or throttle body.
Hence the quandray. The last sentence allows modified hoses, tubes, etc. -- why would anyone modify an intake tube, hose, pipe, etc. UNLESS they were going to speed or ease the flow of air into the intake.
For purposes of disclosure, this is definitely a ME request, but I would remove "velocity stacks" from the second sentence as well to get rid of what I perceive as a conflict with the last sentence of the rule. [/b]
I will disagree. 1st: you are seperating Ram Air and velicity stacks. It says they are both prohibited. Right?

To my reading, the owner removed the part, and substituted it with a stock unit that has been modified.

And he did just that, the point being that it doesn't say you can modify that part. The confusion may lay in that just above that in the rules, modify is specifically mentioned so it was assumed that you couldn't by tech.
