Can any one point me to either a oem replacement or a an aluminum aftermarket replacement. i would prefer it to have the holes for vac lines and what not its for an s4

 

Don't know of any off-the-shelf aftermarket TID you can buy. Most people just make their own. Mine is a 3" pipe w/ a 45* bend that has a piece of 13/16" pipe welded on for the BOV and a 1/4 NPT fitting for the PCV connection. Ebay, McMasterCarr and a machine shop can take care of it for you.

 

I used some random-*** APC one meant for a some kind of honda.

 

Mine also started life as a "cold air intake" for a Honda. I chopped it up and made it into what I needed.
