Rick91GT is absolutely right, he knew about Tiny Avenger before i did
www.tinyavenger.com
This site is focused at Thunderbird Turbo coupes, but in the middle of the product page is a 5.0L mustang elbow tube from the throttle body to the mass air meter. You can get it in either a black finish or chrome, both for $90. I may do that as well if i get a ram-air kit.
