Wow, I didn't realize any manufacturers had done an air to air intercooler for a supercharger, But apparently Mercedes did in 2003!
I would think zipties would get cut through pretty quickly trying to feed them through the radiator slats.
how is the radiator mounted? can you slide the chloroplast in there and re-attach?
Edit: I was trying to find a pic of the intercooler system, and found this link:

It shows the unknown line in your pic is the feed to the intercooler. The slats are likely meant to reduce intake noises.
