K&N filter horns

[Bill Eastman <william.eastman@medtronic.com>]

I keep reading about K&N stubby velocity stacks for the inside of pancake
filters.  Where can I get a set of these, how much do they cost, and what
are the part numbers?  Any experience or testimonials would also be
appreciated.  As we all know, airflow, bodywork, and whiskey are better
when they are smoother.
