OK, but why choose to do something like that when you could just fit a paper filter with more media and retain stock filtration performance and increased air flow?
OR
Install something like a Donaldson PowerCore which flows more than stock OR the K&N, filters better than both of them, and is also basically a lifetime filter, particularly in an automotive application.
Widman posted some pics a while back of PowerCore retrofits on some vehicles and I was really impressed with his thought process. They are arguably the best air filter out there, the issue seems to be they lack the "bling" of a gauze filter/CAI setup. And of course they are pretty large. But then so are many of the big cone/heat shield combo's that get installed.
The Donaldsons sound like a good alternative to K&Ns...just never heard of them...I will look into them...
Here's Richard's (widman) thread with some pics:

I went to their website and unfortunately they don't have a vehicle application guide...
