TB cover: Form or Function?
 

Ok so I have nothing better to do...
Does anyone know if the plastic cover over the throttle body has any function?
Or just form.
I used to think the "skidplate" under the engine was just to keep dirt out but was wrong.
So before I shelve the TB cover to remove a teeny tiny bit of mass from my car I thought I'd ask.

Form....

It's nothing but bling. I'm just glad Subaru exercised some restraint in the plastic department. Have you ever seen the new RX8 Renesis engine? No you haven't; it's completely hidden by a monstrous cover; no aluminum showing at all - no alternator, no intake, Nada!

The huge covers are more function than form, they are primarily for noise reduction.
