Exactly.  I did this:

but just for fun.  K&N gets you a cool sticker, but unless you have an
intercooler, there is nothing for it to "cool."  A nifty ram air set up
like mine looks pretty, and that is important, but it was probably good
for about .3 hp at WOT and high speed.

The K&N has a smaller filter element area than the paper elements, and
forces you to do one of the more awkward jobs on these cars more often
(in order to clean and oil it).
