Uhh, I don't think that particular set-up is going to be plug-n-play.
I'd assume the GM intake was designed w/ an airbox (I think that the
pre-'90 TPI had a MAF sensor in the intake, and the '90+ TPI didn't, but
what do I know...I'm a VW guy) and the K&N is a drop-in panel filter. 

If you want a K&N cone filter, those can be had from Summit Racing, or
just about any race shop or catalog. You could probably adapt a Japanese
made (an off the shelf part) Aluminum intake to suit your needs. One
thing to consider though...open element filters like the cone style are
often subjected to hot air in the enging compartment. Since cold air is
more dense than hot air, the oxygen content is greater in the same given
volume of air...a better burn and more power output. That's the general
theory most subscribe to. Cold air is better. 

So, most people fabricate a heat shield of some sort...or route a custom
intake down below the car (and possibly get a ram-air benefit, but watch
those puddles!).
