Performance improvement will probably not be noticable, but you may notice
less noise.

Refitting the missing snorkel made a *huge* difference in interior noise
on my diesel.  (Diesels have a similar snorkel setup, but in the left rear
pillar instead of the right one.)  Now, a gas engine has a much less open
intake tract than a diesel does, but it may still make a noticable
difference.
