doesn't have an airflow sensor, has a manifold pressure sensor instead.

so why does that sensor go to the original airbox then? does it effect the performance at all?

what sensor, you mean the vacuum operated switch for hot / cold air ? You'll find a vacuum line running the throttle body on there, not a wire.
