It looks like some of the Mondeos and MPV's didnt have EGR, but it didnt apply to the Cougars or Contours and I doubt it applied to North American MPV's.
I think EGR is a personal choice as far as whether its a good idea or not. B3nn3tt is right that Ford put it there for a reason. Theoretically it keeps temperatures cooler by poisoning combustion a little bit. It should provide better gas mileage and lower emissions.
It does seem counter-intuitive to add poison into the intake, but its a pretty tried and true automotive design practice. Exhaust gas recirculation - Wikipedia
That hasn't stopped many of us from deleting it...but the automotive engineers would probably say we are wrong for doing so.
Also, you may run into trouble on your MOT and emissions.
Well there might be a different reason that we over here don't know but everyone I talked to said EGR changes so little about gas mileage and emmisons that its negligible. You would still pass emissions and gas mileage will be barely noticeable. And since I am swithcing to a SVT UIM I can just tell MOT the closing plate is just a adapter plate or maybe even remove it completley since most of them have no clue about anything not german especially if its 20 years old. Also there had to be a reason for Ford to delete it on the 2495 engines, because all of the 2544 have it. Weirdly enough the 2495s are a emissions class lower than the 2544s so it can't be that bad since the 2495 work with higher compression which usually means even higher temps doesn't it? Or maybe everything burns better that way..... idk. Nevertheless if its possible I'll delete it. I wouldn't want Exhaust Gases in my lungs so I also don't want them in my combustion chamber.
