Air flow meter

[Cerberus90]

I've read on the decsription for some air filters that there are different models for different versions of car. I would just like to know if all Mk4 Fiesta Zetec 1.25i have an airflow sensor or if they all don't have one or if some do how I can tell if there is one. It has slightly confused me. The airbox is behind the right (looking towards the bonnet form outside) headlight.

I hope that made sense.

Cheers.
