Looks like an alternative opening for the air to be sucked into the engine.

it kinda works abit if connect to the brake hoses...helps with the braking..however, if u realise how the selling price plunge from $200-300 at brand new to $20 as advertised, it kinda explains its usefulness??

Never know this type of air bleed device still exist... it was popular like 6 years ago.
