you can really go overboard under the hood with too many things, IMO...I like the engine to jump out, so I kept it to just a few things - My car being cyber/red, I faced the same thing:

later I painted the fuse cover in cyber gray.
so for your car I would do:
shark gray fuel rails with red corvette lettering
Plenum in black carbon fiber or gloss black
Fuse in shark gray
