whats the purpose of the internal Swan Neck on a Lambretta Airbox?

I tend to dremal them out whenever I can and it appears to give a small gain- could be all in the mind though :D

Any ideas? Its obviously there for some reason.

Hi Chris, originally as an intake noise baffle. If your engine is anything over standard then yes it will make a difference. Provided you're running through the air box of course :lol:
