1. Top left - off the Audi 5000.

2. Off a Porsche 924. Taking a look at the third you can notice the left opening does not have the spacer in there. You can pound that out with a hammer from the opposite side.

3. Another throttle body. (there are even smaller ones on 924's!)

This is the throttle body off of the Audi 5000 series installed on my intake for my Porsche 924. With a complete stock car, you probably won't notice anything (probably not always) but with some other breathing mods this can add a little power. Add a cam and port and polish your head. See the Head page for more information.
