Throttle body air filter?

I was going to try a conical air filter right at the TB opening but the opening is oval and the filter opening is round. Do they make an adaptor or special filters or am I asking a stupid question. I would like to try it before going through the trouble of making duct work for outside air.
It's a '92 Z28 305 TPI with the air flow sensor at the back of the plenum.

Got the KN 5000 under the Xmas tree. Just put it on. I like this, I can put the stock parts in a box in case I want to put it back to stock. Looks cool and, at least in the 30 degree weather here, it seems to help throttle response.

Those filters were intended for TPI retrofit applications. As soon as the radiator heats up, you'll actually lose power.

Yeah, I am going to add ducting to the stock CAI in the Spring. Great in the cold weather right now though and it looks cool for "show and tell".
