Because basically there were two people posting in there that actually were helping you.
If you're worried about it, try different setups. Get the tubing, install it. Then remove it and bolt the filter to the throttle body. It's not going to be any different either way like they stated. The cone on the TB will just make the blower louder at WOT, throttle response might be a little better too.
I do it that way because I'm lazy, it's easy, and the gains for all the extra work with intake piping don't warrant my time.
How's that?
