induction wise if your after more power than noise your better off fitting a pannel filter and having a bigger feed pipe into the air box with the intake possitioned behind the grill. not sure how it is on the 1.6 escort as standard.
could also fit a bigger throttle body say off the 1.8 or 2.0. this would also suit a cam kit well, like a fast road cam or similar. then either a full system or cat back exhaust system and a remap. could see some nice power from all that. if you stayed with standard cams you could get bluefin.
