Hi,
Just wanted to share this with you guys...
Im installing an IK in my 172 MK2, and ive managed to get my hands on an airbox from a MK1 Race car from Portugal. As you can see it has a hand-made carbon "mouth" of 70mm, and 90mm on the other side. Here are the pics:

Dont mind the std airfilter, it came along when i bought the airbox. Im gonna use a JR conical filter or a Green one. Ill update with more pics when i have it installed.
