Need Opinions on Custom 1988 5000 CS TQ intake

Hey everybody my car is in the shop for a valve job so im spending my free time b/t class and work to design a new cylindrical intake for my bastard car (1988 Audi 5000 CS TQ). Im in classes to become a mechanical engineer technologist so im going to any extremes to help my silver betty breathe better. I got the biggest dam K&N filter sold which was for a V8 Chevy Tahoe or something i think and I want to fabricate something to put it in my car. When I bought the car it was chip tuned with the turbo and a hollowed out CAT so I really want it to get some more COLD air since its factory fed from right inside the hot area of the engine bay up front. I think its a really bad design but wutever. Any way I wanted some people's opinions on this idea:

I want to run a series of sewer piping of 45 degree elbows from the factory airbox that cant be removed due to the fact that the MAF is actually a lever action item connected to a plate inside; its hard to describe but its gotta stay there none the less. The K&N drop-in filter the car came with will be removed as well. Any way I want to use a hole saw drill bit of 3 and 3/8th inch to run the piping directly into the box where the factory piping goes in. Then Im going to run three of these elbows into the filter which will be behind a custom (cut trashcan probly from what ive read on the net) heat shield just behind the front passenger headlight assembly. I no longer have the external oil cooler mounted in the car so thats out of the way entirely. My biggest question so far is will it be a problem to put the filter even further from the factory MAF assembly or will it make no difference at all the way this will be set up.

Sorry for the enormous post and thanks for anybody's help in advance. Oh and if you skipped everything else just to read this line, please just go back and read it haha
