3d printing would be an option. Depends on the size of the vents and printer bed size.
Honestly when I get mine I'll probably just cover with a towel on the outside, or drape a couple of towels across the engine on the inside.
If I was super gung-ho about some sort of insert, I would just line the vents with several layers of thicker plastic (like paint drop cloth) and then pour some expanding foam into it to make a molded insert.
I’m thinking other mid engine car owners have been dealing with this for ages. Maybe just throw some towels down either over the vents or underneath the vents. Anyone here a longtime Ferrari owner and can suggest what he or she has been using?
