What do these nuts do

I was replacing my air filter and got curious about what the two screws on top of the engine do. As I was removing the second nut the screw broke off and is stuck inside the nut. What do they do. [IMG][/IMG]

I also lost my right nut. Tried getting it replaced at my service center but they didn't bother so I assume its not important?

pretty sure those are just for aesthetics (or they serve no physical or mechanical purpose). Why would you remove a bolt just to find out what it is for? That mistake probably cost you the price of a new plenum because I am not sure you can buy that piece separate.

By the way your engine bay is very dirty

they don't unscrew. effectively cosmetic. some say they held the plenum as it was glued together.

They do serve a purpose, but it was only to glue it together. And since they are just for aesthetics (now), I would just epoxy it back in place and no one will be the wiser. Unless of course they try to take it off.

I was told that there are rods inside the airbox that connect top and bottom in order to keep the airbox from resonating too much.
