Default porting the plenum

Can anyone give me advice with this. Is it hard to do with a dremel or should I have someone do this for me. If I can do it myself can anyone give me directions as to how to do this.

If I do this will I see a significant gain or is it small. Thanks

BTW It is a 90 A4 with 88000 miles

Its not difficult to do, if you take your time.

I'd rather play golf for the gains you will see.

You're probably right. I burned up my dremel on this, bought another one, but i was unemployed then, so time was cheap.

Siamesing the runner ports was the toughest part.
