Anyone have insight on this? I'd actually like to be able to get the filter up around or above the rack just to keep it out of the mud zone.

I have read that before. The explanation was that jetting the carb was to be difficult/irratic when using an extension longer than 6".
I kind of find that to be odd since the stock intake length on my Yerf was 8"...
But, as you can see the 8" extension yielded almost 1/2 MPH gain over the 6" in the 300' test, and only lost .2 MPH on MAX speed.
That's the best I could come up with
