Either sensor will work but will give you different voltage readings if I remember correctiy. DTR recommends using the later style because of a lower faikure rate. $40-60, buy the Motorcraft part or you might regret it.
2003-early 2004 under turbo:
Drain a couple gallons of coolant. Remove degas bottle. Remove FICM. Remove rear stud on intake manifold so it doesn’t tear your arm up. Use a socket, swivel and extension to get it loose.
Late 2004-on easily removed on passenger valve cover. I forget the socket size but think it is a 15/16” deep

The newer style icp is 15/16". The older style, which I prefer, is 1-1/16" or 27mm. I took a 1/2" drive deep 27mm socket and ground the end down as much as I could without sacrificing full contact with the mating hex surface on the sensor. That and a flexible head 1/2" drive ratchet and its not a bad job. Would be super easy on a lift.
